YMC America, Inc C4-HG guard 120A 10um 20x4mm
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
YMC America, Inc Diol-NP guard 60A 5um 10x10mm
YMC-Pack Diol-NP is a versatile alternative to silica for normal phase separations and provides much better reproducibility when compared to bare silica material It shows typical normal phase retention behavior when used with low-polarity mobile phases due to hydroxyl groups on the surface of the stationary phase acting as polar groups YMC-Pack Diol-NP can also be used in HILIC-mode with organic/water mobile phases
YMC America, Inc ODS-AHG guard 120A 10um 10x4mm
YMC-Pack ODS-A is a high-coverage fully-endcapped C18 phase which exhibits exceptional lot-to-lot reproducibility It is available in three different pore sizes and is suitable for the separation of a wide range of compounds YMC-Pack ODS-A in 120 pore size is used for high performance reversed phase separations It has selectivity for the separation of many organic compounds found in pharmaceutical chemical and biotechnology industries 200 ODS-A offers a unique mix of moderately large pores and high surface area for the analysis of compounds ranging from small organics and pharmaceuticals to moderately-sized proteins
YMC America, Inc C8 guard 120A 10um 20x4mm
YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120 pore material Available in three pore sizes YMC-Pack C8 columns will separate many classes of compounds including pharmaceuticals organic chemicals and biologics
YMC America, Inc C8-HG guard 200A 15um 50x30mm
YMC-Pack C8 columns are prepared using exhaustive bonding of a monomeric octylsilane to totally porous and spherical silica gels The functionalized silica is then treated with an endcapping process which produces a moderate 10% carbon loading on the standard 120 pore material Available in three pore sizes YMC-Pack C8 columns will separate many classes of compounds including pharmaceuticals organic chemicals and biologics
Advanced Materials Technology HALO 1000 Å OLIGO C18, 2.7 µm, 2.1 mm x 5 mm, Guard Column 3pk
HALO BIOCLASS Oligonucleotide columns are designed with the foundational properties of Fused-Core technology for high efficiency, high speed separations and optimized for the needs of oligonucleotide separations. The HALO 1000 Å OLIGO C18 columns deliver superior separation and impurity profiling for longchain oligonucleotides, (up to and beyond 100 nucleotides) with higher peak capacity and lower backpressure. Ideal for advanced applications like CRISPR and therapeutic development. Their robust design supports high pH and temperature conditions, scalable column lengths, andreliable performance for advanced applications The inert column hardware also addresses absorptivity concerns so the highest recoveries can be achieved.
