Features Manufactured with polymer lining and inlet/outlet frits, Mastro TM range of LC columns are an excellent choice for compounds which have phosphate group, or compounds which chelate binding to metal. Mastro TM LC columns is controlled activated of stainless by special internal coating. Highly recommended for LCMS applications in which inertness is critical.
Mastro2 TM C18 Comparing the SUS body column, the inert body column of other companies, and the Mastro2 ™ column using a phosphate group- containing compound, not only the area value of Mastro2 ™ increases, but also the variability is extremely small from the obtained CV value. In addition, since the peak shape is good, the S / N is large and the detection sensitivity is improved.

Unlike other products, Mastro2 ™ has a structure that does not generate metal chelates because all liquid contact parts are PEEK resin. In addition, a line-up of 2.2 µm microparticles is introduced as the PEEK resin parts are designed to be resistant to deformation even under high pressure.
