GPAL strives to consistently meet and exceed the expectations of our clients. Great Plains Analytical Laboratory is known for its high level of analytical expertise in HPLC Lab services. The Sugar Profile analysis for NLEA is performed by HPLC Vitamin D (Cholecalciferol and Ergocalciferol).Vitamin A (Retinol or Retinyl Palmitate).Quantification of Dough Conditioners, and flour bleaching agents Some of the more common tests performed by GPAL’s HPLC Lab are:ĭetection and Quantification of Mycotoxins Great Plains Analytical Laboratory’s HPLC lab utilizes liquid and gas chromatography to assay a broad array of tests, such as Mycotoxins, Vitamins, Sugar Profiles, Cholesterol, and Fatty Acid Profiles, on many different sample types. The HPLC chromatography methods are used to separate complex mixtures into individual compounds, which are then identified and quantified by suitable detectors and data handling systems. HPLC lab analysis has proven to be an optimal technology for many of these applications. Detecting and/or quantifying the vast majority of food analytes according to their relative volatility and polarity are factors that must be considered when selecting an appropriate analytical method for their determination. Mandatory monitoring of these residues is required in order to ensure that they do not exceed the prescribed levels.Īs a result, specific HPLC methodologies have been developed in order to protect consumers. Because of their toxicity, government agencies have set tolerance levels for the nature and concentration of the chemicals and drug residues in food products. Chemical residues can be found in foods of animal origin such as milk, eggs, and meat. While the use of chemicals in modern agriculture and food production have certain benefits, some of these chemicals may pose a risk to humans. Other chemicals used in food production are colorants, preservatives, antioxidants, artificial flavorings and sweeteners, and more. Pesticides that protect crops against weeds and pests contain target analytes for the HPLC Lab to detect and quantify. The primary components in an HPLC system include the solvent reservoir, or multiple reservoirs, a high-pressure pump, a column, injector system and the detector.Īs it relates to the food industry, HPLC instrumentation is used to detect the chemical compounds that are often involved in agriculture. The main purposes of using HPLC is for identifying, quantifying and purifying the individual components of the mixture. Generally, high-performance liquid chromatography (HPLC) is described as a chromatographic technique used to separate a mixture of compounds in the fields of analytical chemistry, biochemistry, and industry. An HPLC Lab tests food for pesticides and other chemicals.
