EPA Method 525.2 Semi Volatile Organics

Method 525.2 is used to determine semi-volatile organics in drinking water and drinking water source. The analytes are extracted from the water using a 47mm C18 disk. The disk is extracted with Ethyl Acetat ...

Application of Stir Bar Sorptive Extraction (SBSE) Coupled to Thermal Desorption GC-MS for Determination of Ultra-Trace Level Compounds in Aqueous Samples

During the past decade, miniaturized and solvent-less sample preparation techniques based on sorptive extraction, e.g. solid phase micro-extraction (SPME), have proven to be simple, fast and environmentally f ...

Determination of PCB, PAH and Chlorophenols in Water using Stir Bar Sorptive Extraction

The analysis of environmentally relevant substances like polyaromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB) or chlorophenols is still an important task for environmental laboratories. The first ...

Membrane-Assisted Solvent Extraction of Triazines and other Semi-volatile Contaminants directly coupled to Large-Volume Injection/Gas Chromatography-Mass Selective Detection

A simple device was developed for in-vial liquid-liquid extraction with a polymer membrane (nonporous polypropylene) separating the aqueous sample from the organic extractant. The membrane consisted of a tubi ...

Improvements in Sample Throughput without Revalidation by Further Reduction of the GC Cooling Time

As previously reported in an Anatune application note, (AS35), the time taken for the GC oven to cool from the end temperature of one run to the start temperature of the next run can be a significant proporti ...

Rapid Large Volume Injection of Selected SVOCs and PAHs in Hexane using the GERSTEL CIS 4+ Injector, the Anatune XLR8R, the Anatune CoolR+ and Agilent 5975B GC-MS

In busy laboratories, there are clean incentives to minimise the instrument runtime. This leads to faster turnaround times, greater flexibility and reduced costs. Also, the elimination of a final solvent con ...

Rapid Large Volume Injection of Selected SVOCs, PAHs and Pesticides in Dichloromethane using the GERSTEL CIS 4+ Injector, the Anatune CoolR+ and Agilent 5975B GC-MS

By injecting a larger than usual volume of sample, improved limits of detection, the elimination of a final concentration step or a combination of both may be achieved. Rapid Large Volume Injection (RLVI) ha ...

Rapid Analysis of Selected SVOCs and PAHs using the Anatune XLR8R, the Anatune Cooling Accessory and Agilent 5975 GC-MS

In busy laboratories, there are clear incentives to minimise the instrument runtime. This leads to faster turnaround times, greater flexibility and reduced costs. To this end, we have developed a rapid meth ...
