This paper describes a unique Prep-rP-HPLC technique that uses a C-18/C-8 derivatized silica coated with a hydrophobic quaternary ammonium salt or quaternary phosphonium salt that acts as an ...

Announcing a new article publication for BIO Integration journal. Esomeprazole (ESO) gastro-resistant tablets (40 mg) are sold under the brand name, Zosa, which effectively manages conditions ...

Reversed-phase HPLC (RP-HPLC) is one of the more popular methods due to its speed, column stability, and capacity to separate a wide range of compounds. Identification of molecules in HPLC is done ...

Most drugs have UV absorption, so the most commonly used detector is the UV detector. Most drugs and endogenous substances are highly polar, and RP-HPLC chromatographic columns can be used to obtain a ...

In this article we will discuss the HPLC analysis of ONs using the Thermo Scientific™ DNAPac™ RP using LC-UV; LC-MS analysis will be discussed in Article 4 of this series. The Thermo ...

Normal phase HPLC is a valuable technique for the separation of polar ... In contrast, for reversed phase (RP) separation these compounds require additional, often time-consuming sample preparation ...
