Bio-inert Materials
Bio-inert Materials
For the 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 science scientists, as they are known for optimum inertness to
biological samples and ensure best compatibility with 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 such as iron, nickel,
cobalt, chromium, molybdenum or copper, which can interfere with biological
samples. The flow downstream of the sample introduction contains no metals
whatsoever.
