Analyte recovery values from spiked cannabis extracts ranged from 102 to 127% with RSD below 12% for 3 replicates. Excellent recovery values were even observed for Aflatoxins B2 and G2 which were spiked at a low level of 6.1 ppb.
The sample complexity makes it important to use highly-efficient, highly-selective phases and columns that are compatible with different detection systems to maximize the information from HPLC experiments. Ascentis Express Fused-Core® columns meet these requirements.
The use of anabolic steroids, such as testosterone, to enhance physical and athletic performance continues to plague competitive sports. Testing is routinely performed on Olympic athletes and Tour de France participants. Reports of baseball stars admitting to using
Apixaban is sold under the tradename Eliquis and at present no pharmacopeial monographs are available for Axpixaban using either an assay and/or organic impurity profiling method. A newly developed and validated HPLC-UV method using a column with C18 solid core
Following the new USP monograph for Famciclovir Tablets, Purospher™ STAR RP-8 endcapped HPLC columns can be used to monitor organic impurities in Famciclovir tablet formulations. Famciclovir is an antiviral drug indicated for the treatment of herpes zoster, herpes simplex virus
Fluorinated compounds possess distinct characteristics that confer desirable physico-chemical properties compared to their non-fl uorinated analogs. Their abundance in pharmaceuticals, chemicals, consumer products and as environmental pollutants dictates the need for a reliable analytical method. Ascentis HPLC columns, by virtue
Understanding the role of chirality in pharmacology became extremely important following the tragedy of thalidomide use in the 1960s. At that time the effect of chirality was poorly understood, and whilst it was discovered that the sedative effect resided in

The most frequently used synthetic sweeteners are: saccharin, cyclamate, aspartame, and sucralose (E955), and this application illustrate the analysis of sucralose from soy sauce following the current Chinese national standard method.
These distinct transporters, NET, DAT and SERT, respectively, are of particular clinical interest because they are the molecular targets for many antidepressants as well as drugs of abuse, such as cocaine and the amphetamines.
