HPAE-PAD Speeds Analysis of Carbohydrates in Beverages & Milk

  
  
  
  
  
  
analysis of carbohydrates in apple cider

The ongoing challenge for food regulatory bodies is not just identifying food contamination problems but also making sure that product formulation and product quality meets regulatory standards and food manufacturers report any ingredients that might impact immune-and allergy-sensitive individuals. By the way, did you know that India has banned the import of milk and milk products from China until June 2015 due to concerns of contamination of melamine? And. you can read about our solutions on the analysis of melamine in pet food and milk (link to post) on this blog.

HPLC Toxiology Research Articles on Analysis of Illicit Drugs

  
  
  
  
  
  
hplc toxicology analysis

I have mentioned before on this blog that I am fascinated by the subject of toxicology and find peer-reviewed articles featuring the use of chromatography, such as the two articles featured here, absolutely riveting. By the way, did you know that the pace at which new and illicit psychoactive substances have been emerged has speeded up tremendously in the last few years?

Gas Chromatography Botany Research Studies (2)

  
  
  
  
  
  
gc-ms botany genetics studies

It has been a while since I have featured chromatography research studies in the field of plant physiology and when I checked the list of peer-reviewed articles from my HighWire subscription, I found I had several fascinating GC-MS studies that would be of interest to our blog readers. So here goes!

UHPLC Techniques Speed Analysis of Herbicides

  
  
  
  
  
  
herbicide analysis hplc

I recently received an email notifying me of a newly released herbicide method featuring the use of our latest UHPLC system (Thermo Scientific Vanquish UHPLC system) and one of our solid-core UHPLC columns (Thermo Scientific Accucore Vanquish C18 1.5 μm UHPLC column), and realized it has been a quite sometime since I shared an herbicide application on this blog. So, here goes!

Automated Solid Phase Extraction & GC Analysis of Pesticides in Water

  
  
  
  
  
  
analysis of organophosphate pesticides

Did you know that the U.S. EPA posts annual reports on quality of drinking water by state? (Link to U.S. EPA site.) Does the regulatory entity responsible for monitoring water quality in your country do so? If yes, do share the link to its site in the Comments box below.

Charged Aerosol Detection Speeds Analysis of Pharma Drug Impurities

  
  
  
  
  
  
carbocisteine impurity analysis

It has been a while since I have written on the analysis of impurities in drug formulations and, here, I am pleased to present a recently published peer-reviewed article featuring a validated HPLC and Charged Aerosol Detection method for measurement of impurities in carbocisteine. This drug is used as an anti-inflammatory mucolytic agent for the treatment of chronic obstructive lung disease and asthma. The European Pharmacopoeia monograph for the measurement of the impurity profile of cabocisteine (downloadable PDF) uses thin layer chromatography (TLC) along with ninhydrin derivatization. Unfortunately, not all related substances occurring through synthesis or caused by degradation are amino acids and are therefore not detected by this approach.

Ion Chromatography Pathogen Research Studies

  
  
  
  
  
  
pathogen analysis using ion chromatography

Here, I am pleased to present two ion chromatography research studies on two common human pathogens, namely Streptococcus pneumoniae (pictured here) and Mycobacterium tuberculosis, that have become increasingly dangerous to humans as a result of their resistance to antibiotics. Indeed, the World Health Organization's (WHO) first global report on antibiotic resistance (link to report) has revealed a worldwide threat to public health and as per their findings this is a serious threat and potentially may affect anyone, in any region of the world. Without an urgent action plan, the world may be en route to a post-antibiotic era, where antibiotics may become ineffective and common infections and minor injuries may have the ability to kill again.

GC-MS/MS Provides Powerful Detection of Low-Level Alkylphenols

  
  
  
  
  
  
surfactant analysis using gc-ms

Here, I am pleased to feature a recently released GC-MS/MS method for the detection of  alkylphenol compounds (link to APE Research Council page) in food and environmental matrices.

HPLC Speeds Analysis of 21 Preservative Compounds in Cosmetics

  
  
  
  
  
  
Analysis of Preservatives in Cosmetics

After the last post on the HPLC analysis of the toxic chemical rhodamine B in cosmetics (link to post), toxic chemicals in makeup have been on my mind a bit; and, when I found the application blogged here, I read it with great interest as it presented the analysis of preservatives, no less than 21 of them, in personal care products!

HPLC Method for Determination of Benzo(a)pyrene in Meat Products

  
  
  
  
  
  
Benzo(a)pyrene in smoked meat

Here, I am pleased to present an efficient HPLC method featuring an improved sample preparation method with fluorescence detection for the sensitive and rapid determination of benzo[a]pyrene (downloadable U.S. EPA factsheet) in complex meat products, such as sausages and preserved ham.
