Explosion-Proof Models

The OMA-300 is offered in two explosion-proof formats:

Exp (Purged) Explosion-Proof OMA-300

Eexp

Eexp systems are purged and pressurized using a certified air-purging device. This method ensures that toxic/explosive gas is not allowed to accumulate inside the enclosure, and is ideal when instrument air is available.

Exd (Cast Aluminum) Explosion-Proof OMA-300

Eexd

Eexd systems are contained within certified explosion-proof cast-aluminum enclosures. This method is more practical if the installation is remote or utilities are unreliable.

Applications

Clean-in-Place (CIP) is a method commonly used to clean the interior surfaces of production equipment. In the process, cleaning solvents such as methanol or water are circulated to sanitize walls, pipes, tanks, etc. To satisfy regulations, the wash must effectively remove all active ingredients from previous production run.

CIP is a stage of significant downtime; production will be stalled until the process is complete. Plants that still use a set duration or depend solely on swab tests are suffering unnecessary downtime and costs. Allowing CIP to run longer than it needs to is an oversight that wastes production time and CIP solvents.

Specific applications include:

  • pharmaceutical production
  • food and beverage manufacture

Technology

Principle of Operation

To analyze the chemical composition of the sample, the OMA uses an analysis method known as ultraviolet-visible (UV-Vis) spectroscopy. The system measures absorbance from 200nm to 800nm and quantifies the amount of light absorbed by the sample at each integer wavlength; the OMA plots this raw data to visualize a high-resolution absorbance spectrum. Learn more

Spectrophotometer Principle of Operation

The OMA uses a long-life xenon 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.

Optical Assembly

User Interface

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

Sampling

The OMA is built for direct analysis of the hot/wet sample, thus simplifying the scope of the sample system and retaining high sample integrity. From our vast experience in sampling design, we know that applications can be similar but are rarely identical. For this reason, we design and build sample conditioning systems on a project basis, working from the process to the drawing board.

The OMA Clean-in-Place Analyzer uses a specialized sanitary flange flow cell for easy sample introduction:
