Carbohydrate Compounds
A carbohydrate is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula Cm(H2O)n (where m could be different from n). This formula holds true for monosaccharides. Some exceptions exist; for example, deoxyribose, a sugar component of DNA, has the empirical formula C5H10O4. Carbohydrates are technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones.
The term is most common in biochemistry, where it is a synonym of ‘saccharide’, a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular weight) carbohydrates, are commonly referred to as sugars. The word saccharide comes from the Greek word σάκχαρον (sákkharon), meaning “sugar”. While the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix -ose. For example, grape sugar is the monosaccharide glucose, cane sugar is the disaccharide sucrose, and milk sugar is the disaccharide lactose.

What we do for You
By altering the ionic form of our polymers (calcium, lead, sodium, silver, and potassium) specific carbohydrate mixtures can be separated by simply using water as your mobile phase. The degree of resin cross-linkage determines the porosity of the polymers therefore enhancing certain separations.
Benson Polymeric recommends using our Pre-Column Heater in combination with our columns because the best separations are usually obtained at elevated temperatures (typical range 30 – 90 Celsius).

Organic Acid Compounds
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. The relative stability of the conjugate base of the acid determines its acidity. Other groups can also confer acidity, usually weakly: the thiol group –SH, the enol group, and the phenol group. In biological systems, organic compounds containing these groups are generally referred to as organic acids.

Using a simple acid mobile phase (typically dilute sulfuric acid), a wide variety of organic acids can be separated without the need of a gradient. By altering the concentration of the acid mobile phase, organic acid separations can be maximized for your particular sample. Benson Polymeric offers two types of cross-linked polymers. The degree of cross-linkage determines the porosity of the polymers which can be used to enhance certain separations. Benson Polymeric also recommends using column ovens in combination with our columns because the best separations are usually obtained at elevated temperatures (typical range 30 – 80 Celsius). By combining eluent strength, temperature and cross-linkage, Benson Polymeric organic acids analysis columns can separate a wide range of samples.
