Dual-Column GC Analysis of Organochlorine Pesticides on SLB®-5ms and SLB®-35ms
The primary column is used to determine presence of the target analytes in the sample; the secondary column of a different selectivity confirms whether a positive match.
Analytical Method for Selenium in Water
Quantify selenium in water using this photometric test and a clear, filtered sample to measure the results at 445 nm.
Analytical Method: Sulfate in Building Materials
Photometric or turbidimetric determination subsequent to water extraction/fusion melting
Analytical Method: Zinc in soils
Photometric determination with pyridylazoresorcinol (PAR) subsequent to acid extraction
Analyze Iron (Total) in Plant Material
The iron test enables quantification of iron ions in various waters. Iron ions are reduced to iron(II) ions that react with a triazine derivative to form a red-violet complex that is measured photometrically.
Improved Determination of Volatile Organic Compounds in Water by SPME and GC/MS: ISO Standard 17943
High performance, reliability, and reproducibility of HS-SPME in combination with GC/MS for the determination of VOCs in water was proven in an interlaboratory trial. The new ISO 17943 using HS-SPME is an improvement on existing official methods for this determination
Determination of Ammonium in Soils
Ammonium is the naturally preferred source of nitrogen for plant growth and there is an increasing global demand for organic food products.
Determination of Silver in Water and Wastewater: Photometric Determination Using Phenanthroline Method and Eosin Y
The article describes the sample preparation and photometric determination of silver concentration in water samples using Spectroquant® photometers and test kits.
Determination of Triclosan in Environmental Waters
Triclosan was detected in waste water plant discharge using HPLC followed by UV and MS/MS detection.
