For easier more efficient testing, this method requires the 16 mm vial/test tube adapter (P/N: 52213) and Pyxis Lab® 16mm prepared extraction vials with pre-filled extraction solvent. The solvent used in this method is 3M ethoxy-nonafluorobutane. It is a non-flammable, low toxicity solvent.
Procedure
- Insert the 16 mm vial adapter into the HM-900 sample compartment, make sure the text on the adapter is right-side-up.
- Prepare the extraction solvent bank:
- Using a pipette add 3 or 6mL of deionized water (DI Water) to a Pyxis Lab® 16mm extraction vial with pre-filled extraction solvent.
NOTE* Users may choose 3 or 6mL of sample depending on the projected concentration of oil. (e.g. for higher concentration samples use 3mL)
- Shake the vial for two minutes
- Let the vial settle for one minute. This will be your solvent blank vial.
- Place the extraction solvent blank vial into the 16mm vial adapter.
- With the 16mm icon highlighted, press the OK key to measure the solvent blank.
- Select an oil type (i.e. calibration curve) desired for this test.
- Once an oil type is selected, use the left or right key to select the test range of the selected oil type. LR indicates the low-range test, HR indicates the high-range test.
- With ZERO highlighted, press the OK key to measure the blank solvent.
- Prepare the sample:
- Using a pipette add 3 or 6mL (whichever was used for the solvent blank) of the sample to be tested to another 16mm extraction vial with pre-filled extraction solvent.
- Shake the vial for 2 minutes.
- Let the vial settle for one minute. This will be your prepared sample vial for final measurement.
- Place the sample vial into the adapter.
- With READ highlighted, press the OK key to measure the oil concentration with the extraction solvent.
- Multiply the displayed value according to the sample volume listed in the user manual to calculate the final oil concentration in the sample.
