Introduction

Bio-inert Materials

For the Agilent 1260 Infinity Bio-inert LC system, Agilent Technologies uses

highest quality materials in the flow path (also referred to as wetted parts),

which are widely accepted by life scientists, as they are known for optimum

inertness towards biological samples and ensure best compatibility to common

samples and solvents over a wide pH range. Explicitly, the complete flow path

is free of stainless steel and free of other alloys containing metals like iron,

nickel, cobalt, chromium, molybdenum or copper, which can interfere with

biological samples. The flow downstream of the sample introduction does not

contain metals at all.
