This application note presents a fast and robust liquid chromatography method to simultaneously test nine widely used additives. Among the additives tested are: preservatives (benzoic acid, sorbic acid, dehydroacetic acid and methylparaben); artificial sweeteners (acesulfame potassium, saccharin and aspartame); flavoring agent (quinine); and a stimulant (caffeine).
Ginseng has been used as an herbal medicine in Asia for over two thousand years for its purported various health benefits, including antioxidant, anticarcinogenic, antiinflammatory, antihypertensive and anti-diabetic. The pharmacologically active compounds behind the claims of ginseng’s efficacy are ginsenosides; their underlying mechanism of action although not entirely elucidated appears to be similar to that of steroid hormones. There are a number of ginseng species, and each has its own set of ginsenosides.
This application describes an analytical method for the chromatographic separation and quantitative monitoring of seven primary cannabinoids, including THC and THC-A, in cannabis extracts by HPLC with PDA detection. Naturally occurring cannabinoids, the main biologically active component of the cannabis plant, form a complex group of closely related compounds, of which 113 are known and 70 are well described. Of these, the primary focus has been on ?9-tetrahydrocannabinol (THC), as the primary active ingredient due to its pharmacological and toxicological characteristics, upon which strict legal limits have been enforced.
In this application, we describe a technique for the monitoring of six cannabinoids, including THC and CBD, in hemp seed oil by HPLC with PDA detection. Figure 1 shows the chemical structures for the six cannabinoids. In recent years, scientific knowledge regarding the composition and health benefits of edible hemp products has significantly increased. Hemp seed oil has been promoted as a good source of nutritious omega-6 and omega-3 polyunsaturated acids, and may be a cleaner, more sustainable alternative to fish oil.
Water polluted by herbicides leach and runoff can cause human health problems including cancer tumors, reproduction deformity, disruption of the endocrine system and DNA damage. This application presents a sensitive and robust liquid chromatography method to test nine widely used herbicides (Figure 1), using a 3 µm UHPLC column to achieve very high throughput at a low flow rate to reduce testing time and solvent consumption. The throughput is compared to that of a conventional C18 HPLC column. Method conditions and performance data including precision and linearity, are presented.
Speciation studies can provide comprehensive information regarding ion mobility, bioavailability, and toxicity. Consequently, many modern labs are expanding their analytical portfolio to include HPLC-ICP-MS. For such studies, it is advantageous to have an intuitive, user-friendly system that meets the user requirements for automation, ultra-low baseline, powerful integration, and flexible data export. And no one offers a more integrated, versatile, and inert speciation solution than PerkinElmer - accelerate your speciation analysis with the NexSAR™ HPLC-ICP-MS Speciation Solution.
