Traditional mass spectrometry ionization methods such as electronic spray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI), are popular methods for detecting the molecular weight of proteins, peptides, and other biologics. The reason being both...

Loss the contact closure signal
our 7600 couple with nanoLC Ultimate 3000 via contact closure. it has run without any loss connection during the batch. Just yesterday, the last injection keep equilibrating system until the LC finished the gradient run. We closed the software and power off LC and MS then started again but it did not help. The Dionex engineer also checked their LC and triggerring cable found both are ok.
Echo MS system maintenance operations
The Echo® MS system is a robust platform, and like any other platform, requires some routine maintenance on a regular basis. Here are 3 maintenance steps that can help you ensure consistent, reliable performance: Immediately before use or after switching carrier...
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
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...
The honey sting
As a consumer it’s hard for me not to feel inundated with claims that our food is “all-natural” or “chemical-free” or that we should buy certain “superfoods” for their health benefits. We read labels and trust that the product we are buying is what we are truly...
Innovation that’s blasting through limitations in explosive detection
Mass spectrometry’s important role in identifying explosives The need for rapid explosive detection is now an unfortunate reality. The remit is multifaceted. The first is for preventative purposes, to protect us from any threat to life. The second is in the...
A new generation of therapeutic modalities
There are over 7,000 genetic diseases that could potentially be cured using gene therapy. Rare metabolic diseases, autoimmune disorders, cardiovascular disease and cancers are some of the top disease classes that can be addressed with gene therapies. With over 1,000...
Enhancing Biologics with CESI-MS Characterization
Comprehensive characterization of a biologic requires analysis at both the intact and digest levels, but these analyses can be complex and cumbersome. For example, with conventional liquid chromatography separations, researchers are often left with limited information...
Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?
For many of you working to develop gene therapy drugs, you know that the time to market the drug is critical. Because gene therapeutics cure diseases by targeting specific genes, it is a constant race to see who develops the drug first. Unlike other classes of drugs where multiple medications can be used to treat a disease, whoever is first to develop a gene therapy drug wins.
Accurate mass LC-MS/MS for PFAS analysis without needing a blockbuster budget
If you’ve been following our recent blogs, you’ve probably seen quite a bit on how per- and polyfluoroalkyl substances (PFAS) are shaking up both the food and environmental industry. Even if you’ve not been following our blogs, you’ve probably seen a lot of media...
A rising star in food allergen research: proteomics of shellfish allergen
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

Analyze Large Omic Data Sets with Cloud Computing and See What More You Can Accomplish
Our scientific world is expanding. With each passing day, new discoveries are made, old discoveries are verified, and more data are generated. Large data sets are now the norm for omics experiments such as genomics, transcriptomics, proteomics, and metabolomics....
Simultaneous Detection of Multiple Species in Meat Using LC-MS/MS Technology
Smart food shopping starts with labels. However, what if we told you the ingredient list may not be all that it seems? According to Food Safety News, producers are sneaking lower quality ingredients into our food to save money. This type of food fraud is estimated to cost the global food industry $10 to $15 billion per year. If you think back to the Middle Ages, even our ancestors were consumed with cost savings by inserting nutshells, seeds, berries, and more within their spices.
Using Mass Spectrometry to Screen Hundreds of Known and Unknown Metabolites
In the field of metabolomics, you typically choose to identify and characterize as many compounds as possible in an unbiased fashion, or screen for a specific set of compounds that are biologically relevant to your research. The beauty of the TripleTOF® System is that...
MultiOmics Research For the Study of Placental Development
A recent study by Katy Williams (UCSF), Christie Hunter (SCIEX), and Andrew Olsen (Advaita) used the iPathwayGuide within the OneOmics cloud computing environment to help understand how placental development can go awry during certain pregnancy complications such as pre-eclampsia.
This LC-MS/MS Application Detects Almond and Peanut Allergens in Spices
If you suffer from peanut allergies, you may want to think twice before diving into a bowl of something spicy. The reason being, some shipments of North American and European products containing ground cumin, cumin powder, cayenne pepper, paprika, and pilli-pilli...
Mass Spectrometry Detects Very Low Levels of Chemical Compounds in Asia Pacific Waters
Did you know that even though most of the world is covered in water, access to clean drinkingwater remains a problem? Take Asia for example where 62,000 people have lost their lives between 2001 and 2005 due to water-related disaster and illness. Clean water is...
Simultaneously Detect Different Types of Beer Microbes Using XP-PCR
Spoiler Alert – How to Save Time Testing for Bacteria in Beer? Nothing ruins a batch of beer worse than bacteria, specifically Pediococcus and Lactobacillus. Too much of these hop resistant genes can get carried away causing spoilage and sour beer. It is why breweries...
