Separation type: Liquid Chromatography Mixed-mode

Succinic acid is a key intermediary (in the form of its anion, succinate) in the electron transport chain, a process that is the key power source for our cells. It also has a few limited functions outside of the mitochondria. Glutaric acid is a common plasticizer precursor and often used in the production of polyester polyols and polyamides. Interestingly, it is significantly more water soluble than either Succinic or Adipic acid. Adipic acid, also known as hexanedioic acid, is a key precursor to nylon, and more than 2.5 billion kilograms are produced every year. Methylmalonic acid is a key intermediary in the anaplerotic reactions of the Krebs cycle. These Dibasic acids can be separated, retained, and analyzed on a mixed-mode Newcrom B column with a mobile phase consisting of water, Acetonitrile (MeCN), and Sulfuric acid (FA). This analytical method can be UV detected at 200 nm with high resolution and peak symmetry.

Methylmalonic Acid is an organic acid with the chemical formula  C₄H₆O₄. It works as an intermediate in the breakdown of certain amino acids and fatty acids. Elevated levels of Methylmalonic avid can be a sign of a Vitamin B12 deficiency or Methylmalonic acidemia, which is a rare genetic disorder where the previously mentioned acid is not properly metabolized, leading to its accumulation.

Malonic Acid is an organic acid with the C₃H₄O₄ chemical formula.  It has a variety of uses from synthesis to preservatives. When it comes to synthesis, it is often used in industrial means. and especially dyes for natural fibers. Besides industrial use, in laboratory environments, it is used in preparation of tris-maleate, sodium maleate buffers, and maleate salts.

Methylmalonic Acid, Malonic Acid can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a triethanolamine buffer. Detection is performed using UV.

Gluconic Acid is an organic acid with the chemical formula C₆H₁₂O₇. It is naturally found in fruits. Industrially, it is found in honey that is produced by fermenting starch. Typically, it is used in food, beverage, cosmetic, and skin care industries.

Malic Acid is an alpha hydroxy acid with the chemical formula C₄H₆O₅. It is most commonly found in fruits and wines. It is sour, which is partially why it is often used as a food additive. Besides food, it is also used in skin-care as an exfoliant.

Citric Acid is a naturally occurring organic acid found in citrus fruits; it is also an intermediate in the citric acid cycle of aerobic organisms. It is used industrially as an acidity regulator, flavoring, detergent, and more than 2 million tons are produced annually. It’s chemical formula is C₆H₈O₇.

Tartaric Acid is an organic acid with the chemical formula C₄H₆O6. It is found in fruits like grapes and tamarinds and is a vital component of wine. It is also used in metal cleaning, as an antioxidant, and as an acidulant.
