About the Gas Clean Filter System

The Agilent Gas Clean Filter system delivers high purity gases to your analytical instruments, reducing the risk of column damage, sensitivity loss, and instrument downtime. The filters are designed for use with the GC, GC/MS, ICP-OES, ICP-MS, LC/MS, and any other analysis instrument using carrier gas. Six filters are available, including CO organics trap (charcoal).

Components

The Gas Clean Filter System consists of a connecting unit and filter (Figure 1). The connecting unit is equipped with inlet and outlet connectors for the gas lines, and two needle-like valves that automatically start the flow of gas once a filter is attached. The filters come filled with dry nitrogen and are made from a heavy-walled polycarbonate sealed at the base with PTFE. When installed onto the connecting unit, the needle-like valves puncture the PTFE seals and allow gas to flow through the filter.

Features

The Gas Clean Filter System delivers the following features and benefits:

• Cleaner gas, longer instrument life, greater sensitivity, higher data accuracy, and overall long-term stability for your instruments and analyses.

4 User Manual

Filter types

• A high-flow connecting unit that handles flow rates up to 20 L/min for collision gas

applications and supply gas for ICP-MS, ICP-OES, and LC-MS.

• A fast-stabilizing and absorbent filter material.

• Filter housing constructed with a transparent and virtually unbreakable, heavy-walled

polycarbonate material.

• The ability to change the Gas Clean Filter without tools or gas shut-off.

Filter types

Each Gas Clean Filter type is designed to filter out a specific impurity that may exist in the gas supply. The following filter types are available:

•Carbon Dioxide - Eliminates CO analyzer, and improves sensitivity and accuracy in TOC analysis.

•Oxygen - Prevents oxidation of the GC column, septum, liner, and glass wool.

•Moisture - Delivers faster stabilization times for increased GC productivity, and prevents

hydrolization damage to the stationary phase, column, liner, glass wool, or septum in the GC.

•Process Moisture - Prevents oxidation of GC components and is safe to use with acetylene in process GC applications.

from supply gas to the Total Organic Carbon (TOC)

•Charcoal - Removes organic compounds and ensures correct performance of FID detectors in the GC.

•Carrier Gas - Delivers faster stabilization times for increased GC productivity, removes oxygen, moisture, and hydrocarbons from the carrier gas for MS applications, and provides ultimate GC column protection.

•Sulfur - Removes water and sulfur specific compounds such as H gas streams for the SCD.

configurations.

Safety Information

General gas safety

• Wear eye protection when using compressed gas to avoid eye injury.

• Fasten all compressed gas cylinders securely to an immovable structure or permanent

wall.

• Store and handle compressed gases in accordance with relevant safety codes.

• Do not put gas cylinders in the path of a hot air vent (including a GC oven exhaust).

• Perform periodic leak checks on supply lines, fittings, and pneumatic plumbing to prevent a

potentially hazardous condition.

Cleaning

Wipe away dust and residue using a lint-free cloth.

Once the filter is consumed, the filter and filter material cannot be replenished or reused.

Recycling the product

When filters are replaced, they must be treated as chemical waste and disposed of according to local policy.

User Manual 9

Installation

Before you begin

Be sure to choose a centralized installation location where all instruments are easily reachable and where the filter’s indicating material is always visible.

Gas Clean Filter connecting units are available for both 1/4-inch and 1/8-inch gas lines. Be sure you have selected the appropriate connecting unit to use with your lab setup.

Prepare your instrument

Prepare your instrument by doing the following:

1 Lower any heated zone temperatures on your instrument to less than 100 °C.

2 Set any purge flows on your instrument to 400 mL/min.

3 If your system pressure is higher than 7 bar (100 psi), reduce the pressure.

Install the connecting unit

The connecting unit can be mounted on a laboratory bench top, affixed to the wall (with optional wall-mounting bracket for the single filter connecting unit), or mounted to the back of a 7890, 9000, 8860, or 8890 GC (with the respective Gas Clean Carrier Gas Kit).

• If you wish to install your connecting until to a laboratory bench top, see “Installing on a

laboratory bench top” below.

• If you wish to install your connecting unit to a wall, skip to “Installing on a wall” on page 11.

• If you have the Gas Clean Carrier Gas Kit for 7890 (CP17988) and wish to install the

connecting unit to the back of a 7890 GC, skip to “Installing the Gas Clean Carrier Gas Kit

for 7890” on page 17.

• If you have the Gas Clean Carrier Gas Kit for 9000 (CP17995) and wish to install the

connecting unit to the back of a 9000 GC, skip to “Installing the Gas Clean Carrier Gas Kit

for 9000” on page 19.

• If you have the Gas Clean Carrier Gas Kit for 8860 and 8890 (CP179880) and wish to install

10 User Manual

Install the connecting unit

1 Remove the two black plastic caps by pushing a thin, narrow object (such as a paper clip)

Figure 2. Removing the plastic caps from the connecting unit

from the bottom of the connecting unit into the underside of the caps until they pop out (Figure 2).

2 Determine the best location on your laboratory bench top to install the connecting unit and

filter.

• Make sure the filter’s indicator is clearly visible so that exhausted filters can be easily

identified.

• Make sure you have ample space above the bench top and connecting unit for

installation and removal of the filter.

• Make sure the gas lines reach the location and will not interfere with other activities in

the chosen installation location.

• Check that the mounting screws will not penetrate any dangerous objects such as gas

and power lines.

3 Place the connecting unit in the chosen location, and use a screw driver or power drill to

install the screws into the bench top through the two openings on the top of the connecting unit.

4 Replace the black plastic caps on the connecting unit to cover the two screw hole

openings.

Installing on a wall

This option is only available for a single filter connecting unit using the optional wall mounting bracket.

Gather the following:

• Wall mounting bracket kit (CP7981)

• Flathead screw driver

• Hex wrench (4 mm)

• Power drill with 5-mm od drill bit

• Pencil

User Manual 11

Install the connecting unit

To install the wall mounting bracket:

1 Determine the location on the wall where you wish to install the wall mounting bracket.

2 Hold the wall mounting bracket against the wall in the location that you plan to install it,

• Make sure you have ample space above the mounting bracket with connecting unit

installed for installation/removal of the filter.

• Make sure the gas lines reach the location and will not interfere with other activities in

the chosen installation location.

• Check that the mounting screws will not penetrate any dangerous objects such as gas

and power lines once installed.

and use a pencil to mark the drilling location for the screw holes (Figure 3).

Figure 3. Mark the drilling locations on the wall using the screw holes in the wall mounting bracket

as a guide

Lay the mounting bracket down on a flat surface.

3 Using a power drill with a 5-mm od drill bit, drill about 5 cm into the wall in both locations.

Wipe away any excess dust and residue.

4 If required, install the supplied drywall anchors into the drilled holes, and make sure each

anchor is flush against the wall’s edge (Figure 4).
