In this issue
Welcome to the Chrom Vision. In this edition, we will like to share with you the experience in HPLC-to-UHPLC method transfer and the analysis for monitoring of fermentation broth during ethanol production and rapid quantitation of aflatoxins in corn by HPLC. Lastly, on top of these discussions on HPLC, we will show you the analysis of phthalates in childrens' products by GC/MS. | |

Share experience in HPLC-to-UHPLC method transfer to improve productivity
 Over the past few years, there has been tremendous interest in approaches to speed up and/or increase the resolving power of the analytical separation process, particularly with the development of columns packed with porous sub-2 µm particles used in very high pressure conditions (namely UHPLC, for ultra high pressure liquid chromatography). Many laboratories want to transition some of their conventional HPLC methods to fast UHPLC methods, but their lack of experience sometimes acts as a deterrent to trying.
In this white paper, we share our experience in HPLC-to-UHPLC method transfer in the form of a tutorial introductory guide to help those who want to try this new and exciting UHPLC methodology to improve their productivity. Read More... | |

HPLC analysis for the monitoring of fermentation broth during ethanol production as a biofuel
Increased ethanol production as a biofuel is leading to a paradigm shift around the world. Renewable biological resources that can be converted to biofuels are rapidly gaining interest in the energy industry as potential alternative fuel sources. This is not just a U.S. phenomenon - it is accelerating globally. In particular, resources such as corn, sugar beets, sugar cane, grains, sorghum, molasses and others (all renewable energy sources) are being converted into ethanol at an ever increasing scale.

GC/MS analysis of phthalates in children's products
Plastic is a well suited material for the manufacture of a wide range of products. Children's products, from plates and cups to mattress liners and diapers and toys, are made of plastic, as a result of its low cost and durability. The manufacture of plastic products often includes additives which are intended to modify the physical properties of the polymer. Common additives are plasticizers, antioxidants and flame retardants. There are a number of different compounds classified as plasticizers - the most common are phthalates. Read More...

Rapid quantitation of aflatoxins in corn by HPLC with Kobra Cell derivatization and fluorescence detection
Very low level detection of mycotoxins in agricultural products has become increasingly important. Mycotoxins are very resistant fungal metabolites that can remain in foods after processing and, sometimes, even after cooking. They are considered potent carcinogens and can be found in many varieties of foods. Of the mycotoxin class, aflatoxins are considered especially harmful, being both acutely and chronically toxic. Aflatoxin B1 and B2 are some of the most potent hepatocarcinogens known. Along with aflatoxins G1 and G2, even extremely low levels of these aflatoxins in the diet are important public-health concerns. With this in mind, this application brief describes a specific, robust HPLC method for the low-ppb detection of aflatoxins B1, B2, G1 and G2 in corn. Read More...
