When testing diesel range organics
(DRO) in water, 10 mL of the water sample is measured out and transferred to
an extraction jar. 10 mL of methanol solvent is then added to the jar and
the extract is shaken for about one minute, giving the solvent ample time to
dissolve the contamination. The sample is then poured into a glass cuvette
and placed into the UVF-3100 for analysis, which is calibrated using
Sitelab's EDRO Calibration Kit (CAL-042) on the Slot A optics.

Sitelab's DRO samples arrived in a
cooler on ice and were provided in both 40 mL VOA vials and a 1
Liter bottle (pictured below). Samples contained deionized
water spiked with commercial grade No 2. diesel fuel.
The certified spiked concentration was 3.62 mg/L.
Sitelab's DRO was 3.78 mg/L.
