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

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 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.

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.

This application introduces the automated analysis of fluorescent diastereomers of the proteinogenic D/L-amino acids using derivatizing reagents with chiral structures.

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.
