Jon MacGregor by Jon MacGregor | 0 CommentsI have a turbo v ion source that shows a glowing blue/purple light at the tip of the Heated Nebulizer corona discharge needle, even when it is not in use and turned out of ion path as it should be when using TIS probe. It only happens in negative mode. It is not arcing to the cutain plate, just a slight noticeable glow at the tip of the corona needle when observed through the front window. My FSE has rebuilt the HN probe and components and also installed a new TIS probe. Still glows when in negative mode. Note also having poor sensitivity in negative mode as well and jagged peak shapes during infusion. Any ideas? Are the symptoms related?
EchoMS OPI Leakage Issue by Amanda Bergamin | 1 CommentWhat is the best way to determine if a recurrent OPI leak during standard operation is due to a faulty/ fouled OPI probe head or a fouled/damaged electrode or poor flow rate optimization?

A rising star in food allergen research: proteomics of shellfish allergen by SCIEX Community | Blogs, Food / Beverage, Life Science Research, ProteomicsIt’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
