Application Notes: General

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.

Sampling and analysis of a challenging range of trace-level volatile & semi-volatile vapours of per- & polyfluorinated alkyl substances (PFAS) in air using TD–GC–MS

The effect of various ion pairing reagents (amines and acidic counterions) on the LC–UV and LC–MS analysis of oligonucleotides (ONs) has been studied.

Use software to deconvolute LC–MS spectra from complex samples and identify unknown components.

Plasticizers added to water bottles to add stability to the bottles can be unknowingly extracted in drinks leading to possible endocrine interactions. 

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 provides an example of a novel food authenticity workflow that can be used for food classification and detection of food fraud.

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

This study shows how centrifugal partition chromatography can produce a high-quality standard of [6]-gingerol without the use of silica-based chromatography methods.

This methodology demonstrates an efficient approach for identity and stability testing of lipids and lipid-based formulations like mRNA vaccines by HPTLC.

This white paper will illustrate how integrated pump controllers optimize pump performance by automatically controlling flow or pressure.

This app note demonstrates the application of Empore C18 StageTips to high pH peptide fractionation in global proteomics with enhanced peptide/protein identification.

With a new electrochemical cell, complete reduction of inter- and intra-disulfide bonds in mAbs is achieved. For cystine knots peptides, the sequence coverage was 100%.

The performance of hyaluronic acid is closely tied to its molar mass, intrinsic viscosity, and molecular conformation, quantified absolutely by multi-detector SEC.

Using sorptive extraction to extract aroma compounds from honey, with automated statistical analysis to uncover differences and determine markers of authenticity

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.

Monovalent and divalent cations in tap water were analyzed by IC YS-50.
