YMC America, Inc ProC4 120A 3um 150x.075mm 1/16
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers The wide pore butyl chemistry allows minimal distortion of tertiary conformation for large biomolecules and results in samples that are pure concentrated and high in biological activity
YMC America, Inc Tri C8 Acc 120A 1.9um 50x2.1mm
YMC-Triart phases are based on organic/inorganic hybrid particles that combine the high mechanical stability and efficiency of a silica-based packing material with the robust chemical stability of a polymer-based packing material This versatile resin is produced using tightly controlled particle formation technology adapted from micro-reactor technology The resulting uniform particle and pore size distributions as well as the smooth surface greatly contribute to excellent peak shape and separation reproducibility In addition YMC-Triart materials are highly resilient and robust when used at extreme pH elevated temperature and high pressure
Mac-Mod MAC-MOD Chiral Cel-2, 5 µm, 4.6 x 100 mm Column, for Reversed-Phase Use
MAC-MOD Chiral HPLC, UHPLC and SFC Chiral Columns are an exciting range of Amylose or Cellulose coated Reversed-Phase or Normal Phase columns proud to be manufactured in the USA. These columns should be your first choice when scouting new selectivity options to improve resolution of racemic enantiomeric mixtures. These columns are also an excellent choice to compare with current Chiral column offerings to see if novel bonding and packing methods can improve resolution. MAC-MOD Chiral columns offer a wide range of novel chiral selectors as well as similar chiral selectors to industry standard chiral columns. However, all chemistries should be tried to ensure proper screening of chiral selectors due to proprietary silica manufacturing and packing mehtods that may still deliver increased resolution to industry standard comparisons.
