{"product_id":"horiba-ocma-500-oil-content-analyzer","title":"Horiba OCMA-500 Oil Content Analyzer","description":"\u003cp\u003eThe HORIBA OCMA-500 is a benchtop oil content analyzer that measures the concentration of oil in water automatically. Inject the water sample and solvent, press start, and the instrument carries out extraction, measurement and draining on its own — there are no drainage valves to open and close and no evaporation step to supervise. It replaces the earlier OCMA-310.\u003c\/p\u003e\n\n\u003cp\u003eMeasurement uses solvent extraction followed by non-dispersive infrared (NDIR) absorption. Because the solvent is never evaporated, light oils such as gasoline and toluene are not lost during analysis — a well-known source of error in n-hexane gravimetric methods, which drive off low-boiling-point fractions before the oil can be weighed. Results are read directly as oil concentration, with no weighing and no gravimetric calculation.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFully automatic cycle: extraction, measurement and drainage at one button press\u003c\/li\u003e\n\u003cli\u003eSolvent extraction with NDIR detection — retains volatile and low-boiling-point oils\u003c\/li\u003e\n\u003cli\u003eComplies with ASTM D7066\u003c\/li\u003e\n\u003cli\u003eUses S-316 extraction solvent, which is not regulated under the Montreal Protocol\u003c\/li\u003e\n\u003cli\u003eConsumes 20% less solvent than the previous generation, lowering running costs\u003c\/li\u003e\n\u003cli\u003eOperates on 8 mL of solvent with 16 mL of measurement liquid, or 10 mL with 20 mL\u003c\/li\u003e\n\u003cli\u003eColor graphic LCD and backlit extraction tank so you can see conditions inside the tank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePart number 3200555915.\u003c\/p\u003e\n\n\u003ch3\u003eOCMA-500 or OCMA-550?\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eOCMA-500\u003c\/strong\u003e performs the extraction internally and automatically — the right choice for routine oil-in-water testing on liquid samples, where you want to hand the instrument a water sample and walk away.

The SR-305 solvent reclaimer recovers and reuses spent S-316 and pays for itself quickly at moderate sample throughput. B-heavy oil (specific gravity 0.895 at 20 °C) is used to prepare span calibration liquid, and tridecane is also available for span solution preparation.
