β-Gone β-Glucuronidase Removal 96-well plates and tubes are designed to target and remove β-glucuronidase from hydrolyzed urine samples without requiring additional time or method development. In a single step and in less than 1 minute, your hydrolyzed samples are ready for analysis.
VIDEO: Important Message from the Global Council of Finger Safety
No actual fingers were harmed in the making of this propaganda video. The Global Council of Finger Safety is not a real council because we have yet to be recognized Continue Reading
Recap: SoCal Dietary Supplements Chromatography Forum
Last month, Phenomenex hosted the SoCal Dietary Supplements Chromatography Forum—an all-day assembly co-sponsored by Alkemist Laboratories and US Pharmacopeia (USP) to discuss “the need and approach to modernizing USP dietary supplement monographs,” particularly those based upon chromatography.
Best and Worst Organic Solvents to Use in LC
There are several critical characteristics to take into consideration when choosing the appropriate organic solvent to use in liquid chromatography. For example, high viscosity solvents may produce backpressures that are too high for the HPLC system used.
What the HILIC is HILIC?
Hydrophilic interaction liquid chromatography (HILIC) is a chromatographic mode used mainly for the separation of polar compounds that are too hydrophilic to be retained in a reversed phase column.

Addressing Cannabis Research Challenges with Gas Chromatography
With marijuana decriminalization on the rise in the United States, many people might expect to see more sophisticated systems of labeling and identification in their newly sanctioned cannabis products. Easier said than done.
Poor Sample Recovery? You May Be Over-Drying
For most reversed-phase solid phase extraction applications using a silica-based SPE media, cartridges are initially conditioned using an organic solvent such as methanol, followed by rinsing with water or a buffer.
Technical Tip: Peak Apex Flattening
Peak shape issues at the apex of a peak are typically related to detector saturation. This symptom can be observed as flattening and/or noise at the peak apex.
Technical Tip: Principle HPLC Conditions for LC/MS
High-performance (or pressure) liquid chromatography, more commonly known as HPLC, can be a useful tool to assist in the improvement or simplicity of mass spectral detection and analysis.
