Analysis of TPH in Soil (Part 2)

Introduction

Previously, we introduced the “Analysis of TPH in Soil (Part 1)” in Application News G247, which discussed the “Oil Pollution Measures Guideline” and the “Policy for Action on Oil Odor and Oil Slick Problems due to Contamination of Soil with Mineral Oils by Landowners, etc.” as announced by Japan’s Ministry of the Environment in June 2006. Moreover, we described the “TPH Test Method using GC-FID” (hereafter, “Guideline”) which is contained in Volume 2 of this Guideline, under the Technical Material Part 2 Specialty Section, Chapter 1 Situation Ascertainment Investigation, and specifically introduced the on- column injection method for analysis of TPH in soil using the 0.53 mm I.D. wide-bore column. This Application News introduces the other analysis method for TPH in soil prescribed in the same Guideline, using the splitless method with a 0.32 mm I.D. capillary column (where column temperature program starts at 35 ̊C).
