{"product_id":"horiba-ocma-550-oil-content-analyzer","title":"Horiba OCMA-550 Oil Content Analyzer","description":"\u003cp\u003eThe HORIBA OCMA-550 is a benchtop oil content analyzer for samples that have already been extracted. You inject the extracted sample into the supplied cell, set the cell into the instrument, and read the oil concentration directly. It replaces the earlier OCMA-350.\u003c\/p\u003e\n\n\u003cp\u003eBecause extraction happens outside the instrument, the OCMA-550 handles sample types an automatic in-line analyzer cannot: oil residue rinsed off machined components, oil adhering to soil and other solids, and any sample where you control the extraction chemistry yourself. The door opens and closes one-handed so a cell can be loaded without putting anything down.\u003c\/p\u003e\n\n\u003cp\u003eMeasurement uses non-dispersive infrared (NDIR) absorption of the S-316 solvent extract. There is no evaporation step, so light oils such as gasoline and toluene are not driven off during analysis — the error that undermines n-hexane gravimetric methods on volatile hydrocarbons. Results read out directly as concentration with no weighing.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExternal extraction — you control the extraction, ideal for solids and surface residue\u003c\/li\u003e\n\u003cli\u003eNDIR detection retains volatile and low-boiling-point oil fractions\u003c\/li\u003e\n\u003cli\u003eComplies with ASTM D7066\u003c\/li\u003e\n\u003cli\u003eUses S-316 extraction solvent, not regulated under the Montreal Protocol\u003c\/li\u003e\n\u003cli\u003eOne-handed door operation for quick cell loading\u003c\/li\u003e\n\u003cli\u003eColor graphic LCD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePart number 3200577566.\u003c\/p\u003e\n\n\u003ch3\u003eOCMA-550 or OCMA-500?\u003c\/h3\u003e\n\u003cp\u003eChoose the \u003cstrong\u003eOCMA-550\u003c\/strong\u003e when your samples are extracted externally — residual oil on components, oil in soil and solids, or bespoke extraction procedures.
