Applications

With thousands of units shipped since 1994, the OMA-406 Rackmount Analyzer has been deployed for a wide range of applications across various industries:

Specialty gasses

The OMA-406 Rackmount Analyzer uses a dispersive UV spectrophotometer for measuring the concentrations of fluorine, chlorine, hydrogen sulfide, sulfur dioxide, ammonia and other gas mixtures from ppm to percent levels. The full spectrum analysis of the OMA-406 enables a single analyzer to be calibrated for multiple ranges and for multiple analytes. Specialty gas manufacturers can leverage the versatility of the OMA-406 to simplify quality control procedures.

Measuring F2/Cl2 in excimer laser gas mixtures

Premixed cylinders containing blends of XeF or KrCl, for example, are produced by specialty gas companies for sale to companies that operate excimer lasers. The quality of the excimer laser gas cylinders must be closely monitored during their production. In addition, the mixed cylinder must be validated, and the halogen gas needs to be quantified.

The OMA-406 Rackmount Analyzer continuously outputs both F2 and Cl2 readings, providing new measurements approximately every 5 seconds. Response time is critical in the production of excimer laser gas mixtures in order to respond to sudden changes in product quality.

OMA technology

Spectrophotometer Principle of Operation

To analyze the chemical composition of the sample, the OMA uses an analysis method known as absorbance spectroscopy. Depending on the target chemicals for analysis, the OMA uses either UV-Vis (200-800nm), SW-NIR (400-1100nm), or InGaAs (1550-1850nm) sensors in its spectrophotometer. The system measures absorbance across its wavelength range and quantifies the amount of light absorbed by the sample at each integer wavelength; the OMA plots this raw data to visualize a high-resolution absorbance spectrum.

OMA process analyzers Principle of Operation UV Vis NIR spectrum detector
OMA process analyzers UV/Vis/NIR spectrum detector

The key difference between a spectrophotometer and conventional photometers is that photometers use ‘non-dispersive’ methods whereby measurement wavelengths are physically isolated using filters. For measuring multiple components, this will require the photometer to employ a moving part (filter wheel) or multiple line source lamps. By contrast, our spectrophotometer is solid state and has a single light source.

OMA process analyzers spectrophotometer light source path flow cell diode array Principle of Operation
OMA process analyzers spectrophotometer light source path, flow cell, and diode array

The OMA uses a long-life xenon or tungsten light source to transmit a signal through the sample fluid in the flow cell. The signal is carried by fiber optic cables from the analyzer to the flow cell, where the chemical mixture of the sample has unique interactions with the light based on its current composition.

The path of the light signal

The measurement cycle of the nova II is virtually instantaneous, but it is helpful to explain it in stages:

  1. The white light signal originates in the pulsed xenon light source.
  2. The signal travels via fiber optic cable to the entry point of the flow cell, where a collimator narrows the light beam. The signal travels directly across the flow cell path length, interacting with the continuously drawn process sample fluid.
  3. Now containing the distinct absorbance imprint of the current chemical composition in the sample, the signal exits the flow cell on the opposite end through a collimator and travels via fiber optic cable to the spectrophotometer inside the analyzer enclosure.
  4. The holographic grating physically separates (disperses) the signal into its constituent wavelengths, focusing each wavelength onto a corresponding photodiode within the 1024-element diode array.
  5. The light intensity spectrum measured by the diode array is processed by the analyzer CPU. The absorbance spectrum is calculated and visualized by plotting lost light intensity at each wavelength due to the process sample interactions.

From xenon lamp to diode array, the entire cycle occupies a few milliseconds and involves no moving parts.

nova II Spectrophotometer

The nova II is the heart of any spectrophotometric Applied Analytics system. This device performs absorbance spectroscopy by transmitting a light signal across the path of a sample fluid via fiber optic cables. The nova II’s wavelength domain of spectral acquisition is known as UV-Vis/SW-NIR (shorthand for ultraviolet-visible / shortwave near infrared).

Major sub-components

  1. The light source. The standard 200-800 nm model nova II uses a pulsed xenon lamp.
  2. The slit. This refers to the narrow aperture in the plate located at the focus of the spectrophotometer lens. It is exactly the size of one photodiode in the array, thus ensuring that each wavelength band is projected only onto the corresponding photodiode.
  3. The holographic grating. Physical separation (dispersion) of the received light signal and spectral imaging onto the diode array are both accomplished by the concave holographic grating. The angle in which the light is dispersed is proportional to the wavelength, such that each wavelength is differentiated and imaged onto a different point in the diode array.
  4. The photodiode array. The linear array contains 1,024 light-sensitive elements, each measuring an assigned wavelength; all the measurements occur in parallel such that the raw data comprises a complete spectral acquisition.

How the OMA detects a chemical

An absorbance curve is like a distinctive fingerprint for a chemical, determined by its unique electronic and molecular structure. The OMA uses powerful software to isolate the absorbance curve of the measured chemical from the total sample absorbance.

User Interface

Our proprietary ECLIPSE software processes the raw spectral data to provide real-time concentration readings. The operator can easily navigate between views (trend graph, spectrum, and more) using intuitive touch-screen navigation. You can also configure alarms, data logging, and outputs.

ECLIPSE™ Software

ECLIPSE is Applied Analytics’ proprietary analysis software platform which provides a touch-responsive visual interface for the operator. The software processes the raw absorbance data from the detector to visualize real-time sample absorbance and output chemical concentrations.

This feature-rich interface allows for easy configuration of display settings, data logging, Auto Zero, alarms, and more. ECLIPSE also contains proprietary multi-component analysis algorithms for measuring up to 5 chemicals simultaneously.

Features

Auto-Zero. Zeroing is a software task which measures the light source emission spectrum when a zero-absorbance fluid is in the flow cell. Any difference in light intensity from this ‘baseline’ while running on process sample will be measured as absorbance. This serves to normalize the detector reading and stabilize accuracy such that re-calibration is never required.

Alarms. ECLIPSE provides multiple configurable alarms for concentration thresholds and other process conditions.

Virtual PLC. There is no need for any PLC knowledge because this functionality is virtualized in an intuitive visual interface, where relay tasks can easily be sequenced and saved.

Trend graph. Easily adjust the historical interval to observed trends in all active measurements.

Data Logging. ECLIPSE writes concentration data as well as spectral absorbance data to log files on the solid state drive.

Multi-Component Analysis

The OMA can be configured to measure up to 5 chemicals simultaneously. The system uses a de-convolution algorithm which separates the absorbance curve of each analyte from the total sample absorbance by solving a regression matrix sourced from hundreds of diodes (one per integer wavelength).

One critical advantage of full-spectrum analysis is the ability to isolate multiple absorbance curves from the total sample absorbance. This allows us to measure multiple chemical analytes simultaneously with a single analyzer, without using filters or moving parts.

Detailed explanation

Let’s look at the example of measuring H2S and SO2 simultaneously: We can isolate the curve of H2S from the total sample absorbance spectrum. This is extremely useful for background correction — when lurking components in the process stream have overlapping absorbance with the target analyte. The high-resolution raw data allows for de-convolution of up to 5 chemical species, meaning that the OMA can be optionally configured to monitor additional chemicals.

Multi-Component Analysis OMA Process Analyzer measuring H2S and SO2 simultaneously
Multi-Component analysis.measuring H2S and SO2 simultaneously.

As illustrated above, each measurement wavelength contributes an equation to a matrix which is continuously solved by the ECLIPSE multi-component algorithm. Due to the resolution of the spectrophotometer, this procedure isolates the absorbance curve of H2S with very high accuracy and is not susceptible to cross-interference. Each equation takes the form:

A’(x+y) = A’x + A’y = e’xbcx + e’ybcy

Where A’ is the absorbance at wavelength ‘, e’ is the molar absorptivity coefficient at wavelength ‘, c is concentration, and b is the path length of the flow cell.

For example, the equation for measuring H2S and SO2 simultaneously at wavelength 225 nm:

A225′(H2S+SO2) = A225′H2S + A225′SO2 = e225′H2SbcH2S + e225′SO2bcSO2

The OMA’s ECLIPSE™ Software continuously solves a matrix of these equations sourced from all measurement wavelengths simultaneously to produce an extremely accurate analysis. False positives and cross-interference are eradicated by the statistical averaging effect of using so many confirmation wavelengths.

Photometers that offer multi-component analysis will often use crude techniques like rotating “chopper” filter wheels or a group of line source lamps. These solutions implement moving parts that are prone to malfunction and multiple light sources that all require replacement, while delivering inferior accuracy.

Through the power of rich data, the OMA provides robust multi-species measurement using a solid-state design and a single light source.

Inherent Safety

Most analyzers draw the process sample directly into the analyzer enclosure for analysis, which is dangerous if the sample fluid is toxic, explosive, or corrosive. The OMA design is unique: we bring the light to the sample, not the other way around. The sample circulates through the external flow cell, which receives the signal via fiber optic cables.

The major safety flaw of many process analyzers is that they bring toxic sample fluid into the analyzer enclosure for analysis. Not only does this expose system electronics to higher corrosion effects, it also poses a lethal threat: if there is any leak in the instrument, especially inside a shelter, the human operator is placed at enormous risk.

Applied Analytics design centers on inherent safety. The key difference between our instruments and other process analyzers is the use of fiber optic cables and external flow cells: we bring the light to the sample instead of bringing the sample to the light. The toxic sample fluid is only required to circulate through the dedicated flow cell, and never enters the analyzer electronics enclosure.
