VOC analysis in soils – Extending SPME to SPME-trap and SPME-trap with enrichment.

2020
<p>The ability of an agricultural soil to function and sustainably provide an increasing food supply for a rapidly increasing global population has become of vital worldwide importance. Traditionally, soil health has been determined on a physico-chemical basis with biological characteristics often being ignored.

Phytoscreening with SPME: Variability Analysis

International Journal of Phytoremediation, 2015
Phytoscreening has been demonstrated at a variety of sites over the past 15 years as a low-impact, sustainable tool in delineation of shallow groundwater contaminated with chlorinated solvents. Collection of tree cores is rapid and straightforward, but low concentrations in tree tissues requires sensitive analytics.

Solid Phase Microextraction (SPME)

The Chemical Educator, 1997
Solid phase microextraction (SPME) was developed to address the need for a fast, solvent-free and field compatible sample preparation method. It has been applied to a range of applications including environmental, industrial hygiene, process monitoring, clinical, forensic, food and drug analysis.

Mercury determination — SPME and colorimetric spot test

Talanta, 2001
A colorimetric method to determine mercury >20 ng (absolute) in eluates of soils, wastes and waste water was developed. For the elution and the analytical determination only 40 min are needed and the determination can be carried out on site. Due to the low Austrian and German regulatory limit levels of mercury (0.01 mg/1000 g solid phase) it needs to ...

Development of new SPME fibers by sol–gel technology for SPME-HPLC determination of organometals

Analytica Chimica Acta, 1999
Solid-phase micro-extraction (SPME), has advantages of simplicity, low cost, ease of use and rapid pre-concentration and extraction compared to other sample preparation techniques. The technique has found limited use in high performance liquid chromatographic applications because of the unavailability of fibers that are stable and durable in strong ...
