Agilent 7890B GC is a dynamic partner for the 5977B MSD, with its efficient protocols and fully synchronized MS operation. MassHunter Software puts you in control – and makes your GC/MSD ...

A GC/MS procedure was developed for the analysis of all major constituents of glycoproteins. The rationale for this approach is that by using GC/MS analysis of the constituents as heptafluorobutyrate ...

Quality control systems are essential in analytical chemistry, especially metabolomics studies. QC systems have been tested for gas chromatography–mass spectrometry (GC–MS) analysis of amino acids in ...

Agilent J&W HP-5ms has very low bleed characteristics that are ideal for GC/MS. The column has excellent inertness for active compounds, including acidic and basic compounds, and improved signal ...

气相色谱质谱联用 (GC-MS) 是一种结合了气相色谱和质谱两种强大技术的分析技术，用于分离、鉴定和定量挥发性化合物。因此，它非常适合分析许多相对低分子量的化合物。虽然气相色谱质谱联用 (GC-MS) 可用于分析固体、气体和液体样品，但其最常用于分析挥发性和半挥发性化合物。 在气相色谱法 ...

The samplers were then analyzed by thermal desorption-comprehensive two-dimensional gas chromatography-time-of-flight-mass spectrometry (TD-GC × GC-TOFMS). Individual cutaneous VOCs and semi-VOCs ...
