Application Notes: Environmental

A study done in collaboration with the Orange County Water District (OCWD) for a direct comparison of manual vs. automated SPE sample preparation in EPA method 537.1

A wide variety of LC column chemistries were evaluated to demonstrate new chromatographic approaches to complex PFAS analyte lists.

In a commercial laboratory setting, excellent precision and recovery in EPA Method 533 for the analysis of PFAS in drinking water was demonstrated.

We demonstrate a highly efficient method to monitor Persistent Organic Pollutants (POPs) and separate them from matrix. Common method of analysis utilizes a GC-HRMS or a GC-MS/MS to accurately quantitate and separate toxic dioxins and furans.

Detection and recovery of 268 multi-pesticide compounds using a robust and reliable analytical method ensure consumers' safety according to regulatory standards.

We demonstrate fast PCB analysis using a single GC column as a way to prevent switching from multiple columns and help reduce instrument down time during PCB analysis.

Spinach and other highly pigmented vegetables contain chlorophylls, carotenoids, xanthophylls, and anthocyanins. Chlorophylls have the greatest adverse effect on gas chromatography systems due to their non-volatile characteristics. This QuEChERS procedure uses ChloroFiltr to significantly reduce chlorophylls without sacrificing the recoveries of planar pesticides.

PFAS are known to be persistent in the environment. Detecting low levels of PFAS in drinking water is made easier using an Activated Carbon Delay Column.

The Agilent MassHunter Optimizer software for GC Triple Quad (GC/TQ) can help generate multiple reaction monitoring transitions for newly added compounds.

This application note describes the analysis of volatile organic compounds (VOCs) analysis in soil and sediments using a headspace sampler and GC–MS system.

Thermal extraction desorption-gas chromatography–mass spectrometry method automation, increased sample throughput, for quantifying microplastics in environmental samples

Data creates alternate testing protocol for U.S. Environmental Protection Agency for GC–MS analysis of tetra- through octa-dioxins and furans equivalent to EPA Method 1613B

The SI-36 4D does not require organic solvent to achieve the separation. Gradient conditions and phosphate ions are eluted within 15 minutes, so analysis time is short.

Oxyhalides and anion standards in tap water were analyzed successfully using IC SI-52 4E. This is applicable to analyzing sources like rain, river water, and runoff.

The application successfully separates the 7 typical ions including F-, Cl-, NO2-, Br-, NO3-, PO43-, and SO42-, and it fulfills US EPA Method 300.1 (A) requirements.

The seven main anions can be separated quickly using the IC NI-424 column. Improvement has been made in the separation of chloride and nitrite ions.

Fused-Core® Technology benefits PFAS analysis for fast, efficient, and rugged separations which are paramount to environmental analysis.

HALO® PFAS and PFAS Delay columns are application verified columns well suited for challenging environmental sample analysis.

High resolution separation of 24 PFAS compounds using the HALO® PFAS Delay column coupled with the HALO® PFAS analytical column.

High throughput analysis of 33 PFAS compounds found across EPA methods 533, 537.1, and 8327 in under 5 minutes.

HALO® PFAS delay and HALO® PFAS analytical columns deliver rugged, reproducible performance for the most challenging environmental sample matrices.

Rapid and high-resolution analysis of PFAS compounds across EPA methods 537.1, 533, and 8327, using the new HALO® PFAS delay and analytical columns.
