Una completa secuencia de trabajo para la separación mediante HPLC de 17 cannabinoides en diferentes productos del cannabis utilizando la columna Ascentis® Express C18 en un tiempo de ejecución más corto con estabilidad de los tiempos de retención. Más información
Fluorinated compounds possess distinct characteristics that confer desirable physico-chemical properties compared to their non-fl uorinated analogs. Their abundance in pharmaceuticals, chemicals, consumer products and as environmental pollutants dictates the need for a reliable analytical method. Ascentis HPLC columns, by virtue
For efficient therapeutic drug monitoring, it is important for clinicians to have access to fast and robust analytical methods for accurate assessment of drug efficacy. Industrial trends toward highly specific LC/MS applications over traditional immunoassay have resulted in the need
The sample complexity makes it important to use highly-efficient, highly-selective phases and columns that are compatible with different detection systems to maximize the information from HPLC experiments. Ascentis Express Fused-Core® columns meet these requirements.
Extraction and analyses of chlorogenic acid and baicalin active ingredients in traditional Chinese medicine (TCM) according to Chinese pharmacopeia monograph by HPLC with Discovery® C18 column to check:
chromatographic data, linearity, specificity and repeatability, LOQ and LOD
Ammonium determination in acidic solutions with Metrosep C Supp 2 column using the acidic binary IC eluent nitric acid/rubidium nitrate concentrate and the sodium bicarbonate/sodium carbonate suppressor regenerant.
Xanthine is a purine base found in most human body tissues and fluids as well as in other organisms. Methylated xanthines (methylxanthines), which include caffeine, paraxanthine, theobromine, and theophylline, commonly used for their effects as mild stiµlants and as bronchodilators
