Acetonitrile

2009-08-21 09:10:29 – The high rate of chromatography techniques development that occur within the recent years, in the Central and Eastern Europe in particular, caused that POCH company made decision to construct a high purity solvents factory in Poland.

New plant to manufacture solvents of the highest quality parameters had been established in 2006 in POCH Gliwice, where technology and know-how of Labscan Ltd. Company were applied.

Solvents for LC-MS (LC-MasScan®)

Solvents dedicated to liquid chromatography combined with mass detection constitute a new group of high purity solvents. These reagents are the result of increasing requirements related with environment monitoring and lower and lower limits of contamination levels in products of our Customers.

Development of instrumental techniques which can be characterised by higher selectivity and sensitivity comparing to methods used in the past, entail detection of lower and lower levels of concentration of examined substances. Together with development of apparatuses, reagents develop as well. This development applies to solvents which can be characterised by low levels of halogen derivative contaminations not higher than 5ng/l as lindane (GC-ECD) and 10 ng/l as ethyl-parathion (GC/PND). Moreover, these solvents contain low content of metal ions:

Sodium Na+ – max 0,1 ppm

Potassium K+ – max 0,1 ppm

Calcium Ca2+ – max 0,1 ppm

Magnesium Mg2+ – max 0,1 ppm

Solvents for HPLC (HPLC-Chromoscan®)

These solvents are dedicated for high performance fluid isocratic and gradient chromatography and represent the biggest group of solvents offered by POCH.

They can be characterised by:

great ability to dissolve a sample and the wide range of the offer guarantees free selection of the best solvent for the tested sample,

high quality, repeatability of parameters in series that guarantees repeatability of analyses results,

lack of contaminations at the UV transmittances declared in specifications, that guarantees lack of “ghost peaks”,

stability of base line. Low drift of the base line guarantees detection of even the lowest concentrations of tested substance.

Solvents for determining pesticides residues (GC-Pestican®)

The POCH solvents dedicated for analysis using the method of gas chromatography can be characterised by extreme low content of halogen derivative compounds at level not higher than 5 ng/l.

Analyses using these reagents constitute the best solution for research, control and measurement laboratories that examine samples for the presence of pesticides or insecticides. Low levels of halogen derivative compounds in a solvent guarantee repeatable and unequivocal analyses results – qualitative ones in particular.

Solvents for environmental analyses (GC-Enviroscan®)

Detecting trace quantities of organic substances in environmental tests requires utilization of purified solvents in order not to introduce background to a sample. It is important at the stage of preparing samples for analyses.

Appropriately purified environmental solvents guarantee declared levels of organic compounds contamination (10 ng/ml as toluene GC/FID) and halogen derivatives (5 ng/l as lindane GC/ECD) or trihalomethanes at the level of 1 ppb.

These solvents are dedicated in particular for quantitative and qualitative analyses of pesticides, herbicides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, dioxins and other airborne halogen derivatives.

Dehydrated solvents (Anhydrosan®)

Dehydrated solvents for DNA and peptides synthesis can be characterized by low content of water. Acetonitrile of water content max. 10 ppm draws special attention in this group. In order to provide stability during storing, this solvent is packed in nitrogen atmosphere free of oxygen. Such procedure provides stability of solvent parameters after opening bottle and obtaining repeatable tests results.

Upon Customer request, we offer products with addition of molecular sieves that guarantee stable water content in the products during its use.

Solvents for spectroscopy (Spectroscan®)

POCH S. A. offers new generation of solvents for UV-VIS spectroscopy which are mainly used for organic compounds analyses.

The most important parameter is transmittance/absorbance (permeability). The higher transmittance (lower absorbance), the more transparent solvent is. In order to maintain very high UV transmittance value, all solvents are cleaned and packed under dry nitrogen.
