Available PEEK columns from GL Sciences, made in Japan.
UHPLC-PEEK Columns (Particle size under 3 µm)
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 offer maximum operating pressure
of 80 MPa for sub-2 µm columns achieving rapid analysis for analytes sensitive to frequently used stainless steel columns
