such as column washing or replacement of a guard column or filter.Column Lifetime NexLeaf columns are packed with silica particles. The normal pH limitations are from pH 2.0 to pH 8.0. Extended use at either extreme of pH may shorten the lifetime of the column.www.ssi.shimadzu.com ...
HPLC–DAD-UV analyses were carried out using a Shimadzu Nexera XR® (liquid chromatographer coupled to a Shimadzu UV detector with the diode array SPDM20A, equipped with a CBM20A controller, DGU20A degasser, LC20AD binary pump, CTO20A oven, and SILA20A auto-injector). A Shimadzu LabSoluti...
Boost your separation with Shimadzu's most powerful UHPLC pump. Our goal is to ensure low pulsation, gradient formation accuracy, and retention time reproducibility with our parallel dual plunger design. One LC-40BX3 can deliver two solvents for reliable high-pressure gr...

HPLC vendors have introduced features that minimize carryover through dual needle usage, which increases washing time between analytical runs. On this point, Curtis Campbell, PhD, OEM/VAR business development manager at Shimadzu Scientific Instruments (Columbia, MD), advises users to use a wash solve...
By that time, Agilent (model 1290), Thermo Fisher Scientific (Acela and Dionex Ultimate), Shimadzu (Nexera), and PerkinElmer (Flexar) had introduced their own versions of UHPLC products, and the debate was essentially over with fewer skeptics voicing objections or contrarian theories. As improved...
