Should you bring your PFAS testing in-house?

As the per- and polyfluoroalkyl substances (PFAS) regulatory landscape evolves in the US and across the globe, the interest in PFAS continues to grow. Drinking water and food packaging are under particular scrutiny, and monitoring programs and requirements will continue to expand to include an increasing variety of sample types and PFAS compounds.

A rising star in food allergen research: proteomics of shellfish allergen

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

In Search of the Unknown

In Search of the Unknown

The production of high-quality drinking water entails rigorous treatment and testing procedures. For water suppliers’ laboratories, such as the Zweckverband Landeswasserversorgung in Germany, one of the major challenges is the identification of trace levels of organic substances, which can be achieved with the help of mass spectrometry.

How to Detect Additives in Cosmetics Amongst Ever Changing Regulations

How to Detect Additives in Cosmetics Amongst Ever Changing Regulations

In today’s technical blog, I’m talking about the cosmetics industry so let’s get right to it. According to a Research and Market report, “The Global Cosmetic market was $460 billion USD in 2014 and is estimated to reach 675 billion USD by 2020, growing at a rate of 6.4%.”1 The U.S. leads the pack with a reported $62 billion in revenue earned in 20162. So, what am I getting at? We know earnings are strong and consumers like their products. But the question remains, are these products that you put on your skin, hair, and ingest safe? Such is the thinking of scientists like me and other chemists who are routinely tasked with detecting minimal levels of potentially harmful ingredients in personal care products against ever-changing global regulations.

Single Injection, Routine Antibiotic Testing in Urine Samples

Single Injection, Routine Antibiotic Testing in Urine Samples

The consumption of pharmaceuticals and personal care products is a day to day occurrence. Once consumed the body excretes the remaining part of the compound which is not absorbed. This waste, flushed down the toilet, makes its way through the sewage system before arriving at a treatment facility where it was then processed with chemicals to ensure its cleanliness. Despite being washed, there can remain trace amounts of bacteria, hormones, metals, and antibiotics in whatever you consume, not just water

The Trouble with PFAS in Drinking Water

The Trouble with PFAS in Drinking Water

There has been a string of news articles concerning polyfluorinated alkyl substances (PFAS) in drinking water these days, and I must say, they have my attention. Here is the thing, when you think of drinking water in the United States, for example, crystal clear lakes, rivers, and groundwater along with effective water treatment come to mind. On the flip side, as safe, some supplies may be there are communities such as that of Flint, Michigan, which have been dealing with lead filled pipes for far too long. Contamination was so bad there that residents were provided bottled water for drinking purposes as the state decided who was responsible for replacing the affected water lines.

PPCP Detection in Drinkwater is no Match for the QTRAP® 5500

PPCP Detection in Drinkwater is no Match for the QTRAP® 5500

SCIEX is no stranger to drinking water analysis, and the Environmental Compendium once again addresses the topic in an application note which covers LC-MS/MS with Fast Polarity Switching.   Using the QTRAP® 5500, researchers were able to detect a large panel of Pharmaceuticals and Personal Care Products (PPCP’s) while performing fast positive/negative switching all from a single injection.  Method details go the distance in this application note, as five experiments were called into action for comparison.

Perfluoroalkyl Acids in Drinking Water – EPA Method 537

Perfluoroalkyl Acids in Drinking Water – EPA Method 537

The United States Environmental Protection Agency (EPA), under the 1996 Safe Drinking Water Act (SDWA), requires a new list of no more than 30 unregulated contaminants to be monitored by public drinking water systems. Known as the Unregulated Contaminant Monitoring Rule (UCMR), a new list is published every five years. The last rule, UCMR3, was published May 2, 2012, and is the focus of the following application note, “Analysis of Perfluoroalkyl (PFFA) Acids Specified under the UCMR3 Using the QTRAP® 6500 LC-MS/MS system,” which can be found in the Food and Environmental Compendium.

Polar Pesticide Analysis by CESI-MS for Routine Food Testing – A Poster Talk

Polar Pesticide Analysis by CESI-MS for Routine Food Testing – A Poster Talk

Method development for routine food testing presents many challenges – whether you are looking to increase the speed of your screening or simplify your method there can be different solutions suited to the task at hand. During RAFA 2015 in Prague, Steve Lock, Market Development Manager for SCIEX Separations in EMEA outlines how CESI-MS may be best suited for polar pesticide analysis.

A Reliable Method for the Identification, Quantitation, and Confirmation of Pesticides

A Reliable Method for the Identification, Quantitation, and Confirmation of Pesticides

When carrying out routine pesticide identification tests in your lab how simple is the process of identification, quantitation, and final confirmation from sample to sample? A reliable method designed to generate multiple data sets and confirm sample data in parallel with your test can save an awful lot of time and effort which is especially helpful as the demand for routine testing increases. In this poster talk, Detlev Schleuder, Support Manager for Food & Environmental Markets, explains how the new QTRAP® 6500+ system can optimize your laboratory’s output with this simple method.
