Separation type: Liquid Chromatography Mixed-mode

High Performance Liquid Chromatography (HPLC) Method for Analysis of Fructose 1,6 Bisphosphate

Fructose 1,6-biphosphate, alternatively known as Harden-Young ester, is the main form glucose and fructose take when they enter cells. It is a key component of the glycolysis metabolic pathway and is the product of the phosphorylation of fructose 6-phosphate.
Using a Newcrom B mixed-mode column and a mobile phase consisting of water and acetonitrile with an ammonium formate (AmFm) buffer, Fructose 1,6-bisphosphate can be retained, separated (from fructose 6-phosphate), and measured. Fructose 1,6 bisphosphate can be detected using charged aerosol detection (CAD) with high resolution.

HPLC Method for Glyphosate, Phosphate on Newcrom B by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Glyphosate and Phosphate Ion

Glyphosate is a broad-spectrum herbicide which is used to kill weeds. The presence of glyphosate is strongly regulated by various governing agencies in the US, Europe, and Asia. Glyphosate is characterized by its carboxylic acid and phosphate group on either end.
Glyphosate and phosphate ions can be retained and separated with a Newcrom B mixed-mode column using a mobile phase consisting of acetonitrile (MeCN), water, and formic acid (H3PO4) as a buffer. This method is compatible with mass spectrometry and be detected via a Charged aerosol detector (CAD).

HPLC Method for Sodium, Phosphate, Chloride, Bromide, Nitrate, Sulfate, Iodine, Perchlorate, Iodide on Newcrom BH by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Sodium, Phosphate, Chloride, Bromide, Nitrate, Sulfate, Iodine, Perchlorate, Iodide 

Sodium, which  has a chemical symbol of Na, is a soft alkali metal that is highly reactive.  It is found in abundance in everyday materials like table salt, sea water, and even the Earth’s crust. It is crucial  for the body’s function and fluid balance.

Phosphate, PO₄^3-, is a compound that plays an important part in biological energy transfer. It contains phosphorus, which is also a key component in bones and teeth. It is also a buffer, which helps maintain pH levels in a body.

Chloride is typically used to refer to a compound or molecule that contains a chlorine anion: Cl^–. It is an electrolyte that is essential for bodily functions including blood pH, fluid balance, cellular functions, and more. Imbalance of chloride can indicate underlying health problems.

Bromide is typically used to refer to a compound or molecule that contains a bromide anion: Br^–. It is often found in anticonvulsants, flame-retardant materials, and cell stains.

Nitrate, NO₃^–, is a compound of nitrogen and oxygen. It is essential as a nutrient in plants; therefore, it is often used in fertilizers. It is easily found in leafy greens. While it is important for cardiovascular health, too high of exposure to it can be dangerous.

Iodide, the Ionic form of Iodine, I^– is essential for thyroid hormone production. Lack of it can lead to iodine deficiency disorders. It is typically found in Iodized salt and occasionally as an antiseptic.

Sulfate is an ionic chemical with the formula SO₄^2-. In nature, it is usually found in geodes like gypsum. It is also created in atmosphere from sulfur dioxide. It is used for a variety of applications, but most notably, coloring wood and creating light-reflecting paints.

Perchlorate is an inorganic compound with the formula ClO₄^–. It is most typically used for explosives. For example, fireworks and rocket propellants. Due to it’s water solubility, it can easily contaminate it. When ingested, it can pose a health risk and cause developmental harm.

Sodium, Phosphate, Chloride, Bromide, Nitrate, Sulfate, Iodine, Perchlorate, Iodide can be retained and analyzed using the Newcrom BH stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a Ammonium Acetate buffer. Detection is performed using CAD.

Inorganic and organic ions are usually analyzed by ion-exchange mechanism. In this application, we used short Primesep B2 and Primesep D mixed-mode HPLC columns to retain and separate phosphate and sulfate ions. Both ions are retained by ion-exchange mechanism. Detection technique for analysis of these anions is Evaporative Light-Scattering Detector (ELSD).

Citric acid and phosphate ion are separated by HILIC on Primesep N HILIC HPLC column. Both compounds are very hydrophilic. Citric acid and phosphate ions are well separated with excellent peak shape. Method can be used for quantitation of citrate and phosphate in various formulations. Because of the lack of UV activity, separation can be monitored by LC/MS, ELSD or Corona CAD. Method can be used for other hydrophilic organic and inorganic acids.

Sulfate and phosphate are separated on Primesep B2 and Primesep D column by anion-exchange mechanism. Because both sulfate and phosphate ions are not UV-active, ELSD is used to monitor separation of both anions. Method can be used to quantitate phosphate and sulfate in various pharmaceutical and chemical formulation, products and solution, drinking and ground water. Retention time is adjusted by increase or decrease of buffer concentrations. Two anions can be retained and separated on a very short column due to strong ion-exchange interaction. Method shows good reproducibility and versatility.
