OMA On-site Cleaning Analyzer

CLEAN-IN-PLACE ANALYZER

OMA provides real-time data by continuously monitoring the concentration levels of contaminants during on-site cleaning processes, reducing process downtime, replacing manual inspections, and minimizing resource waste.

Product Features

Performance

Real-time on-site cleaning monitoring It can be confirmed that the T90 response time is less than 10 seconds. No false alarms Full-spectrum analysis avoids errors. Extremely wide dynamic measurement range It can maintain high accuracy even when the sample concentration varies significantly. Fully automated operation under unmanned supervision Automatic purging and zeroing function; optional remote automated control

Save time and effort

No manual detection required. Fully automatic on-site cleaning monitoring Instant verification Don't worry about incomplete or excessive operations. Customize various alarm and communication outputs. 4-20mA analog output, MODBUS; HART, etc.

Usage cost

No consumable materials or reagents. In addition to purging with standard gas, Low maintenance requirements Simply require wiping the lenses once a month. Long-life xenon light source Average service life of 5 years Instrument with an all-solid-state structure Stands out among competitors due to the absence of moving parts.

Compatibility

Application areas

On-site cleaning is a technical method that involves cleaning the internal surfaces of production equipment. During this process, cleaning agents (such as alcohol and water) are used to clean or disinfect walls, pipelines, tanks, and other components. To meet regulatory requirements, this cleaning must effectively remove all residues from previous production runs.

On-site cleaning is performed by temporarily halting on-site production until the cleaning is complete. Many factories still rely on manual methods, such as swab testing, which leads to unnecessary prolonged downtime and substantial resource consumption across the entire production line. The fact that on-site cleaning often takes longer than theoretically expected results in wasted production time and excessive consumption of cleaning solvents.

Specific application areas

Drug production
Food and Beverage Production

Technical concept

Monitoring Principle

The OMA online analyzer uses the principles of ultraviolet and visible spectroscopy to determine the concentrations of chemical components in a sample. The OMA system analyzes the absorbance of the sample across wavelengths from 200 to 800 nanometers, and the data is captured by a 1024-element photodiode array detector and transmitted to a processor for data analysis, yielding high-resolution absorption spectra.

Optical structure

The OMA process online analyzer uses a long-life xenon lamp as its light source to transmit signals that come into contact with the sample via a flow cell. This signal is emitted by the light source and transmitted through an optical fiber cable into the flow cell, where it interacts with the sample gas. Samples composed of various chemical substances exhibit unique absorption characteristics for light. The resulting light signal then exits the flow cell, travels back to the detector via another optical fiber cable.

Absorbance Curve: Light Aromatic Hydrocarbons

To detect the concentrations of benzene, toluene, and xylene, OMA identifies the unique absorbance spectra of pure analytes and uses mathematical methods to separate and isolate the analyte’s absorbance spectrum from that of the sample being measured. Based on Beer-Lambert’s law, OMA correlates the unique absorbance spectrum of each analyte with its actual concentration.

User interface

AAI’s proprietary ECLIPSE software processes the acquired spectral data into actual concentration readings. On the touchscreen controller, the analyzer operator can easily switch between different interfaces—such as trend graphs, spectra plots, concentration readings, and more—and can independently and at any time set and adjust alarms, outputs, purge functions, zeroing, and other parameters.

Safety performance

Most analyzers directly introduce the sample into the analyzer’s housing for measurement. However, if the sample is toxic, highly corrosive, or explosive, this could be extremely dangerous. The OMA design is unique: instead of introducing the sample into our analyzer, we guide the optical signal into the sample itself. The sample flows only through a flow cell and never comes into contact with the analyzer. The flow cell is connected to the analyzer via an optical fiber cable.

Sample system

The OMA series analyzers can directly measure hot and humid samples, simplifying the sampling process. We have extensive experience in hydrogen sulfide analysis, and while many application principles are similar, actual conditions can vary significantly. Therefore, for projects where it’s necessary, we offer customized design of sample pretreatment systems or sampling systems tailored to our clients’ specific needs.

The OMA on-site cleaning analyzer uses a special clean-flange flow cell for simple and rapid sampling:

Optional models

OMA products of various models share the same electronic architecture, and their monitoring functions and performance are identical. The differences among these models lie in their external structural designs and materials used, with the aim of meeting the diverse requirements of different applications.
