Ametek Spectro- Application Note - High Range Oil in Soil Analysis (0.5-10.0%) - Brochure

INSTRUMENT SETUP

1. Turn on the InfraCal 2, using either the 18v power supply or the internal battery.
2. Allow the instrument to warm up for a minimum of 30 minutes. If the instrument has been stored in a location of extreme temperature it may require a longer stabilization time.

EXTRACTION PROCEDURE

1. Materials Needed:
a. Sample collection bottle, preferably glass. Note: the collection bottle should be large enough to hold the sample and the solvent.
b. Graduated cylinder
c. Syringe with filter frit
d. Extraction solvent
2. Collect a known amount of sample. Although any amount of sample above 8 g can be collected, it is important to remember that too small a sample will not be a good representation of the water being tested.
3. The extraction will use a 1:1 ratio. For example, if you collect 25 g of sample, you will need to add 25 mL of solvent.
4. Add the extraction solvent directly to the sample.
5. Shake the sample and solvent mixture vigorously for 2 minutes.
6. Using the syringe filter, filter any solid particulates out of the extract
