Accessories (Sample pretreatment, parts)
Name: Accessories (Sample pretreatment, parts)
Description:One of the causes of a gradual increase of a column pressure after each sample injection is that fine particles in the sample clog the frit of the column. Replacing the column frit is one solution; however it is more convenient to use precolumn filter. Connect a precolumn filter between the injector and the column, check the line pressure occasionally, and replace the precolumn filter when the line pressure increases. Stainless steel precolumn filters are suitable for stainless steel tubing systems. Both PEEK and stainless steel precolumn filters are suitable for PEEK tubing systems.
Hydrogen Columns
Name: Hydrogen Columns
Description:The BP-100, H carbohydrate column is similar to the ion exchange(2000-0, BP-OA, Organic Acids) column, except for a different degree of cross linking and sulfonation. The variation in cross-linking and sulfonation optimizes not only the separation of carbohydrates present in the sample but also the organic acids and alcohols which may be present. Only dilute acid is used as the mobile phase at ambient temperatures.
Calcium Columns
Name: Calcium Columns
Description:The BP-200, Ca carbohydrate column is packed with a low(4%) cross-linked 10µ styrene-divinylbenzene polymer resin in the calcium form. The large pores of the resin resolve oligosaccharides as large as DP-8. This resin also resolves mono and disaccharides in samples such as starch hydrolyzates. These calcium columns find wide use in the corn syrup industry.
Sodium Columns
Name: Sodium Columns
Description:The BP-200, Na carbohydrate column is packed with a low(4%) cross-linked 10µ styrene-divinylbenzene polymer resin in the Sodium form. The large pores of the resin resolve oligosaccharides as large as DP-8. This resin also resolves mono and disaccharides in samples such as starch hydrolyzates. These sodium columns finds wide use in the corn syrup industry.
Silver Columns
Name: Silver Columns
Description:The BP-200 Ag carbohydrate column is packed with a low(4%) cross-linked 16µm polystyrene-divinylbenzene polymer resin in the silver form. Using size exclusion as the primary separation mechanism, the BP-200 Ag column resolves oligosaccharides up to DP-11(degrees of polymerization). These silver columns find wide use in the corn syrup industry.
Lead Columns
Name: Lead Columns
Description:The BP-100, Pb column is packed with a 9µ styrene-divinylbenzene polymer resin in the lead form. Complex sugars are often used to add distinctive tastes to foods and beverages. Pentoses and hexoses found in cellulose products are well separated especially glucose, xylose, galactose, cellobiose, arabinose and mannose. These lead columns are quite useful for the separation of xylose, galactose and mannose which are not completely resolved on the calcium column. In addition, the lead columns resolve sucrose and lactose well if these two sugars are present in excess in some samples.
Potassium Columns
Name: Potassium Columns
Description:The BP-100 K, carbohydrate column is useful in separating betaine from sugars found in beet and cane sugars such as sucrose, glucose, and fructose. Our Potassium Columns also can be used for the analysis of mono-, di, and trisaccharides in corn syrup.
Organic Acid Columns
Name: Organic Acid Columns
Description:Our BP-OA Organic Acid columns are used for determining the anions of weak organic and inorganic acids. Anions of organic acids include acetate, formate, oxalate and others. Anions of inorganic acids include fluoride, bicarbonate, borate, silicate and others. Acids are eluted usually in order of acid strength with the stronger acids eluting last(in order of increasing pKa values). Retention times of the organic acids may be controlled through adjustment of the eluent pH.
