The sMRM Pro Builder template is an Excel-based tool that can help you implement large panels of analytes in your lab. The Excel sheet will take your preliminary experimental results and compute retention times, retention time window widths and dwell time weighting to optimize your targeted assay.
In our previous blogs we discussed the need for a more comprehensive approach for monitoring contaminants in finished drug products.1,2 Here we cover a generalized approach for the targeted, quantitative LC-MS/MS analysis of several commonly encountered nitrosamines in pharmaceuticals and ways to address specific challenges with their analysis.
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
It’s important to know what you’re eating, especially if you suffer from a food allergy.
About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion
Integration of Electrophoresis into a Single, “Plug-and-Spray” Device Offers a New Approach for Metabolomics Applications
Teasing apart the metabolome: CESI-MS separation of small, anionic compounds
Metabolomics, an emerging field focused on the chemical processes central to cellular metabolism gives scientists a snapshot of the cellular metabolic state, or metabolome at a given time. Highly complex, the metabolome contains a large and diverse group of small molecules and requires a systematic understanding of chemical end-products of cellular processes. Used in conjunction with genomics and proteomics information and researchers can gain a deeper understanding of an organism’s physiology. As a result, insights on a disease’s progress or an organism’s health status become clearer. However, there is a caveat. Teasing apart metabolome components and identifying each molecule is a significant analytical challenge that requires specialized applications and approaches able to separate very small, chemically similar analytes from each other.
