High Performance Liquid Chromatography (HPLC) Method for Analysis of Alexidine on BIST B+ by SIELC Technologies
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies
Alexidine is a chemical compound that belongs to the class of bis-biguanide antiseptics. It is known for its antimicrobial properties and is used in various products for disinfection and antiseptic purposes. Alexidine has broad-spectrum antimicrobial activity, and it is commonly used in healthcare settings for its effectiveness against bacteria, fungi, and some viruses.
Topical Antiseptics: In some formulations, alexidine is used as a topical antiseptic to disinfect skin and mucous membranes.
Oral Care Products: It is found in some mouthwashes and oral care products due to its antimicrobial properties.
Contact Lens Solutions: Alexidine is sometimes used in contact lens solutions to prevent microbial contamination.
Wound Care Products: It may be included in certain wound care products for its ability to prevent infection.
Alexidine can be retained and analyzed on a BIST B+ mixed-mode stationary phase column using an analytical method with a simple mobile phase of water, Acetonitrile (MeCN) , and a sulfuric acid as a buffer. This analysis method can be detected using UV at 200 nm.
