Further Details: 

The Model NACC2930 is a fixed wavelength IR spectrophotometer designed to perform repetitive quantitative analysis of total hydrocarbons dissolved in non-absorbing solvent. Both volatile and nonvolatile oily samples can be analyzed using EPA methods 413.2 and 418.1. The instrument accommodates standard IR Grade cuvettes and holders of up to 1432mm. Using a 1432mm cell in the concentration expansion mode permits analysis of hydrocarbon levels as low as 0.05 ppm.

Water and hydrocarbons absorb in the near IR at 3.4 to 3.5 microns (2930 cm-1). By dissolving the oil content of a sample into fluorochlorocarbon (freon), which is nonabsorbing at 3.4 to 3.5 microns, and following the extraction procedure established in EPA methods 413.2 and 418.1, a working curve is prepared using blank solvent (freon) and known standards. Samples are then compared to the calibration curve in direct ppm readings shown on the instrument. Repeatability is +/-1% on identical samples.

The Model NACC2930 can also be used with hexane based EPA method 1664, which is an analysis technique that does not require the use of freon as a solvent. A special cell is an optional accessory for this freon-free technique.
