Effects of Pore Size
The molecular weight of peptides and oligonucleotides are from several kDa to several dozen kDa. It is critically important to select the appropriate pore size column to achieve high efficiency. As shown below, the optimized 200Å pore size silica enables InertSustainBiO C18 to analyze peptides and oligonucleotides.

A Radically New Steel-Coated-PEEK Hardware
Generally, conventional PEEK hardware is tolerable up to a back pressure of 20 MPa. The mechanical strength of PEEK is far less than stainless steel and the durability to be very low as well. As illustrated below, the introduction of a radically new Steel-Coated-PEEK hardware in InertSustainBio C18 offer maximum operating pressure of 80 MPa for 1.9 μm columns achieving rapid analysis for analytes sensitive to frequently used stainless steel columns.
