Melamine in pet-foodDec 23, 2009
Melamine (sometimes confused with the plant and animal compound, melanine or another compound, melanin) is an industrial chemical used in the manufacture of plastic products. Despite that, tests showed that a number of milk companies have used it in processing milk to artificially increase the apparent protein content by addition of non-protein nitrogen and so allowing illegal dilution of the product with water with a corresponding increase in sales value.
Read MoreDetection of Mycotoxins in NutsDec 21, 2009
Mykotoxins are natural metabolism products of molds which have a toxic effect on humans and animals. Just like micro-organisms which generate antibiotics, molds which generate mycotoxins have spread all over the world. Aflatoxins are the most toxic form of mycotoxins. Some types of food show an increased risk of aflatoxin release due to fungal infestation: dried fruit, spices, nuts (peanuts, hazelnuts, pistachios) and grain (wheat, corn).
In many pilot-plant or production facilities temperature control systems are like a wallflower at the junior high school dance – they are not the most technical, expensive or exciting equipment in the room and are easily overlooked. But, when the most popular person in the class asks the wallflower to dance...
Read MoreMycotoxins in NutsDec 11, 2009
Every year during the pre- holiday activities the use of nuts increases in order to prepare for the holiday baking. To a large degree unnoticed by consumers is the problem of a possible contamination of these foods with mycotoxins.
Read MoreParticle sizing with static laser scatteringDec 11, 2009
When determining particle sizes a wide variety of techniques are used in which sieving may be the most popular. Sieving is a relatively simple technique, despite the fact that of course different instrumental approaches can be used. The main advantages of sieving are the low price of the instrumentation and the fact that different fractions of the original sample can be prepared for further use.

Read MoreTrace-level aliphatic amines in pharmaceutical ingredientsNov 6, 2009
The determination of aliphatic amines in interfering matrices is a challenging task because protonated amines are often poorly retained on the column. This problem is met by applying ion chromatography using coupled-column matrix elimination.
Read MoreIon chromatographic analysis of carbohydrates in essential and non-essential foodstuffsNov 5, 2009
This article describes a straightforward ion chromatographic method that uses isocratic elution and pulsed amperometric detection (PAD) to sensitively determine water-soluble polyols and sugar alcohols as well as mono-, di- and oligosaccharides in essential and non-essential foodstuffs. While carbohydrate determination of most foodstuffs requires only minimal sample pretreatment such as dilution and filtration, samples with interfering matrices such as protein-containing dairy products have to be dialyzed prior to injection.

Read MoreMonoTrap Handling Instructions (Version 1-0)Oct 8, 2009
MonoTrap™ is a silica-based adsorptive. This product can be characterized by through pore (due to the monolith structure of the silica base) and a large surface (due to the pores within the silica frame). Active carbon is used as an adsorptive on the silica frame surface to which octadecyl (ODS) group has been conjugated.
