In this article, the author explains the uses of triethylamine as a mobile phase additive in HPLC, with real-world examples from pharmacopoeias and literatural applications.
Formic acid is commonly seen added to the mobile phase in mass spectrometry methods, but have you wondered what specific role it plays, and can other acids substitute it? This article explains the role of formic acid in MS from the perspective of chemical reaction equilibrium thoroughly.
In HPLC analysis, methanol and acetonitrile are the most common organic mobile phases. But have you ever thought about what exactly differentiates them? When should methanol be used and when acetonitrile? In this article, the author shares their thoughts on this matter.
Правильная подготовка, обращение и хранение подвижных фаз для ВЭЖХ имеют решающее значение для получения точных и стабильных результатов. В этой статье рассматриваются основные моменты, касающиеся выбора растворителей, подготовки подвижных фаз и предотвращения распространённых ошибок, которые могут повлиять на хроматографические характеристики и срок службы прибора.
