ABSTRACT

Capillary columns made with less than 1 millimeter (mm) internal diameters (i.d.) offer significant theoretical advantages over conventional 4.6 mm i.d. columns. However, current instrumental constraints and manufacturing difficulties have limited their applications. SMT currently offers a comprehensive range of capillary HPLC columns with 0.1 through 0.5 mm i.d. that are very rugged and highly reproducible. Continue reading

ABSTRACT

High performance liquid chromatography (HPLC) method has been developed for simultaneous determination of Hydrochlorothiazide (HCT), Amlodipine besylate (AML), and Valsartan (VALS) without any pretreatment or pre-purification steps. The method is simple and accurate. Adequate resolution was achieved using SMT, SAM-C18, Catalog number OD-5-100/15 (5µm, 100Å, 4.6mm x 150mm) column, Separation Methods Technologies, Incorporated Continue reading

ABSTRACT
A direct (without derivatization) separation and simultaneous analyses of peroxyacetic acid (PAA) co-existing with acetic acid (AA) and hydrogen peroxide in the equilibrium mixture has been successfully carried out with a reversed-phase high performance liquid chromatographic (HPLC) technique. The method is rapid and utilizes SMT SAM-C8 column (O-5-100/154) and the separation was performed with no additives in the mobile phase in less than 2 mins. Continue reading
