Determination of Olive Oil Adulteration by Principal Component Analysis with HPLC–Charged Aerosol Detector Data
Overview Purpose: To examine the use of targeted principal component analysis (PCA) with HPLC-charged aerosol detector data as a means of determining adulteration of olive oils. Method: Oil samples were analyzed as both untreated and hydrolyzed, using a C30 HPLC method and charged aerosol detection. PCA results were determined using peak area percent values of the acylglycerides and free fatty ...
متن کاملDetermination of intralumenal individual bile acids by HPLC with charged aerosol detection.
An isocratic HPLC charged aerosol detector (CAD) method was developed, validated, and applied for the determination of individual bile acids in human gastric and duodenal aspirates. The method requires a low volume of aspirates (50-100 microl) and minimal sample pretreatment. A Hypersil BDS RP-C(18) column (250 x 4.6 mm, 5 microm particle size) was equilibrated with a mobile phase composed of m...
متن کاملGentamicin Sulfate Assay by HPLC with Charged Aerosol Detection
Introduction Aminoglycoside antibiotics are proven medications for both human and veterinary use with broad-spectrum activity, particularly against gram negative bacteria.1 Many of these antibiotics are manufactured by bacterial culture (fermentation) processes, and as such can be a mixture of active compounds and not a single chemical compound. One example of an antibiotic manufactured by ferm...
متن کاملMonitoring Peptide PEGylation by HPLC with Charged Aerosol Detection
Purpose: The goal of this work was to develop a fast and accurate method to monitor PEGylation reactions by using HPLC with complementary UV/Vis and charged aerosol detection. It is an increasingly common practice to modify biotherapeutic peptides, proteins and small molecules by attaching chemical groups designed to enhance properties such as bioavailability, potency or stability. One example ...
