We focus on improving the quality of capillary chromatography and nanospray interface devices to the mass spectrometer. Improving sample delivery and nanospray ionization can dramatically improve results for all your analyses.

Electrospray ionization (ESI) is a technique used in mass spectrometry to produce ions using an electrospray in which a high voltage is applied to a liquid to create an aerosol. It is especially useful in producing ions from macromolecules because it overcomes the propensity of these molecules to fragment when ionized.

电喷雾电离（Electrospray ionization，ESI）是一种使用电喷雾向液体施加高电压产生气溶胶来产生用于质谱分析的离子的技术。 由于生物大分子相对易碎，它们的结构在解离和电离过程中很容易被破坏。

2012年11月7日 · Electrospray ionization (ESI) generates intact gas-phase ions from analytes in solution for mass spectrometric investigations. ESI can proceed via different mechanisms. Low molecular weight analytes follow the ion evaporation model (IEM), whereas the charged residue model (CRM) applies to large globular species.

This mini-review provides a general understanding of electrospray ionisation mass spectrometry (ESI-MS) which has become an increasingly important technique in the clinical laboratory for structural study or quantitative measurement of metabolites ...

Electrospray ionization (ESI) is a mainstay of LC/MS that can be used to analyze large and small analytes. The Agilent electrospray ion source uses patented orthogonal nebulization and a heated counterflow drying gas system to achieve excellent sensitivity and robust, reliable performance.

ESI is a soft ionization technique used to ionize non-volatile or thermally labile samples amenable to analysis in the liquid phase such as those separated by liquid or ionic chromatography (LC or IC). The ESI source applies a high voltage to the liquid sample stream, generating a fine mist of charged droplets.

2021年4月1日 · Electrospray ionization (ESI) source is routinely used to connect the liquid chromatography (LC) to mass spectrometry (MS) for the analysis of various analytes: from highly polar low molecular weight metabolites to oligopeptides.
