LC 300 HPLC System

Accurate identification and quantification of cannabinoid content is a critical step in the process to bringing safe and high quality cannabis flower and fortified products to market. As the legalization of recreational cannabis use continues throughout the world, fast and efficient liquid chromatography methods for the determination of cannabinoid content are need to satisfy both regulatory and consumer demands.

In this application note, a fast and simple method for the determination of 16 common cannabinoids is presented. Utilizing a PerkinElmer LC 300 HPLC system with a PDA detector, the method results in the elution of all sixteen compounds in under seven minutes, with LOQs = 0.15 µg/mL for most analytes.

Parabens are utilized as an antimicrobial preservative in many commercial offerings including cosmetics, personal care products and foods, and offer both chemical and thermal stability to products. Although parabens increase the safety of products, recent studies have suggested that parabens may exhibit weak endocrine disrupting effects on users of the products, an effect that can be further intensified by the ability of parabens to be absorbed by the skin without being broken done by esterase enzymes.

In this application note, a fast, robust and sensitive method utilizing a PerkinElmer LC 300 HPLC system with Multi-Wavelength UV/Vis (MWD) detector for the analysis of 2-phenoxyethanol and seven commonly used parabens in eight different commercially available cosmetic and personal care products is presented.

Isoflavones are water-soluble compounds found in many plant and food sources. Designated as phytoestrogens, isoflavones are structurally similar to to the female hormone estrogen, and have been shown to exhibit a number of beneficial impacts to human health, such as a reduction in the development of certain cancers, as well as an improvement in cholesterol ratios. Studies also suggest, however, that the phytoestrogenic nature of isoflavones can also lead to an exacerbation of existing thyroid disorders, owing to a disruption to the endocrine system. As such, precise quantification of isoflavone content in nutraceutical products is paramount to ensure label-claim accuracy and consumer safety.

In this application note, an efficient and reliable method for the determination of six common isoflavone compounds is presented. The method, which was developed in accordance with the USP monograph for soy isoflavones in dietary supplement capsules, utilizes a PerkinElmer LC 300 UHPLC system, with subsequent detection of compounds achieved utilizing an LC 300 PDA detector.

Maple syrup, a common natural sweetener, is consumed regularly by households around the world. Quantification of sugar content in maple syrup is paramount to satisfy product labeling requirements and ensure label-claim accuracy. Although sucrose is the primary sugar component in maple syrup, a complete identification and quantification of the other complex carbohydrates, including glucose, fructose and maltose, is essential.

In this application note, a robust and efficient method for the determination of the four aforementioned complex carbohydrates is presented. Utilizing an LC 300 HPLC system, a hydrophilic interaction chromatography (HILIC) technique is utilized with subsequent detection achieved utilizing an LC 300 Refractive Index (RI) detector.

Feed milling today is a complex business, and agribusinesses both large and small need to balance the nutritional and safety needs of livestock with availability of raw ingredients and their seasonality and variability. Add to that the valuable supplementation and medication that millers supply, and it’s clear: you’re creating a complete nutritional delivery system, not just a simple mix of grains.
