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.
