Guardian DC in-line non-return gas filter

The Guardian DC In-line Non-Return Gas Filter P/N 70-803-1942 from Glass Expansion protects your ICP system in two ways:

• A non-return valve prevents acidified sample or rinse solution syphoning into the instrument gas box.
• 30-micron PolyComb filter protects the nebulizer from particulates in the instrument gas supply.

The Guardian In-line Non-Return Gas is positioned between the Ar inlet on the Direct Connection nebulizer and the gas supply fitting on the instrument. The In-line Non-Return Filter has a one-way valve that allows argon to flow from the instrument into the nebulizer but prevents liquid syphoning into the instrument. A unique PolyComb 30-micron filter design protects the nebulizer from particulates from the gas supply or from worn or damaged fittings in the gas lines. Unlike sintered or frit-style filters, the linear honeycomb structure makes PolyComb most resistant to particulate and dissolved solid clogging.

*The Guardian non-return valve is intended for use with gas lines only.
