Compact and simple, HORIBA’s OCMA-350 oil content analyzer delivers quick, accurate measurements in the lab or in the field. It efficiently measures the level of oil in water or soil for environmental applications, checks for residual oil on semiconductor parts which have been cleaned, and measures oil on ayn industrial surface.
Using the OCMA-350 is almost effortless. Simply inject the extract from your sample, dissolved in Horiba’s S-316 solvent, into the measuring cell, and press one button. You can even use your PC to simplify operation.

Environment: Surveying water quality and hazardous waste sites
Industry: Monitoring wastewater influent and effluent
Marine transportation : Checking bilge and ballast discharge
Petroleum processing : Monitoring the efficiency of oil/water separation processes
Oil depots :Monitoring the discharge produced when cleaning storage tanks
Automotive: Monitoring waste-water discharge from service stations
Quality Assurance: Measuring residual oil on textiles and metal parts.

Stable readout
The unit’s data evaluation function analyzes the readings, determines when the value has stabilized, and displays than stable value.

Self-monitoring
Messages on the LCD screen inform you of any electrical malfunctions, irregularities in measurement, and deterioration of parts, so that you can always be assured of proper functioning.

Simplified recordkeeping
The OCMA-350 keeps a record of the time and date of measurement along with each data set it records. When printing out, it provides you with both the time and the measurement, allowing for easy recordkeeping.

1. Choose a reasonably sized sample
2. Measure out an appropriate amount of solvent, and immerse the part in the solvent until all the residual oil has dissolved.
3. Introduce the resulting solution to the measuring cell, and set the cell in place.
4. Press the start button and wait for the results.

The OCMA-350 uses the highly effective, environmentally-safe S-316 extraction solvent to extract the oil components from oily water samples, soil samples or product surface. The extract is analyzed using IR absorbance, a non-dispersive infrared spec-trophotometric technique which is specific to hydrocarbons such as oil.

The OCMA-350 measures absorption in the 3.4 to 3.5 micrometer range. The two graphs at the right show the absorption spectra of (1) petroleum and (2) HORIBA’s S-316 solvent. All hydrocarbons, including oils, absorb infrared radiation at about 3.4 to 3.5 micrometers .The S-316 solvent absorbs no infrared radiation in that range. As a result, the unit can measure any hydrocarbons in the extraction solvent quickly and accurately, with no distortion of values due to the presence of the solvent.

HORIBA’s S-316 Solvent can be recycled with the aid of t he optional SR-300 Solvent can be recycled with the aid of the optional SR-300 Solvent Reclaimer. Recycling the solvent not only cuts your solvent costs, but also helps protect the environment.
