Pyxis 16mm Oil In Water Extraction Vials Pre-Filled Solvent- 12 Pack

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

1. Insert the 16 mm vial adapter into the HM-900 sample compartment, make sure the text on the adapter is right-side-up.
2. Prepare the extraction solvent bank:
   1. 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)
   2. Shake the vial for two minutes
   3. Let the vial settle for one minute. This will be your solvent blank vial.
3. Place the extraction solvent blank vial into the 16mm vial adapter.
4. With the 16mm icon highlighted, press the OK key to measure the solvent blank.
5. Select an oil type (i.e. calibration curve) desired for this test.
6. 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.
7. With ZERO highlighted, press the OK key to measure the blank solvent.
8. Prepare the sample:
   1. 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.
   2. Shake the vial for 2 minutes.
   3. Let the vial settle for one minute. This will be your prepared sample vial for final measurement.
9. Place the sample vial into the adapter.
10. With READ highlighted, press the OK key to measure the oil concentration with the extraction solvent.
11. Multiply the displayed value according to the sample volume listed in the user manual to calculate the final oil concentration in the sample.

Features

• Two Extraction Methods – The HM-900 offers measurement of oil content through Hexane extraction and Pyxis prepared non-toxic /non-flammable solvent, for a safer and more convenient measurement reducing sample preparation steps. Both 24 mm and 16 mm sample vials may be used with HM-900.
• Pre-programmed Calibration Curves for Primary Oil Classes – The HM900 has three default built-in calibration curves for Marine-Offshore Oil, #1 Diesel/Kerosene, and Heavy Fuel Oil. The user may select which of these three formats are desired for final measurement display. Users may also create up to 7 customized/user defined calibration curves for the specific oil desired.
• Suitable for Direct Read Method for Dissolved or Emulsified Oil – The HM-900 can be used to directly analyze oil in water content without the need for extraction using UV fluorescence methodology. This method is commonly utilized for samples containing dissolved or lightly emulsified oil.
• Secondary Standard for Rapid Calibration – Preparation of a true oil in water calibration standard is both time consuming and subject to error. As such, the HM-900 can also be calibrated using Pyxis synthetic OIW (oil in water) secondary standards. This approach enables users to utilize a synthetic oil in water standard for rapid device calibration, improved accuracy and extended shelf life of the calibration solution.

Typical Applications 

• Heat exchanger leakage detection
• Oil tank leakage detection
• Intake water monitoring (UF & RO Feedwater)
• Reinjection water monitoring
• Industrial wastewater monitoring
• Marine discharge monitoring
• Plant runoff / storm water monitoring
