OCMA-350 À¯ºÐ ºÐ¼®°è]
Just by setting the equipment, the OCMA-350 provides highly accurate analysis of
the oil content of water samples from which the oil has already been extracted
in the auxiliary cell. In addition to displaying residual oil and solid body
content suspended in water in a range from 0mg/l-200mg/l, the OCMA-350 allows
users to display analysis results for land in mg/kg and for oil absorbency in
Abs. The OCMA-350 is also well suited for evaluating the capabilities of
semiconductor fabrication and precision machinery cleaning equipment, evaluating
the properties of industrial process oil and the residual oil of polishing
materials as well as wastewater that has been adulterated with silt, sludge, and
other suspended particles.

always choose the proper unit for your sample measurement.
To introduce your
sample into the removable cell, just pull the cell out of its holder. It's easy
to avoid leaks and spills when you have this much control. The removable cell is
also easy to maintain.
All the right connections
Each unit is equipped with a printer port and an RS-232C port.
Simply connect the OCMA-350 to your printer or PC for remote control of the unit
and ready access to measurement data.

||1 Choose a reasonably sized sample |
||2 Measure out an appropriate amount of solvent, and
immerse the parts 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 surfaces. The extract is analyzed
using IR absorbance, a non-dispersive infrared spectrophotometric 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. 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.
HOROBA's S-316 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.
