Manual Overview

This manual contains four chapters and one appendix.

1 Introduction

This chapter gives an overview of the manual and contains safety information.

2 Site Preparation

This chapter provides the requirements for preparing the site before installing the Headspace Sampler. It covers the requirements for temperature and humidity, space, power, gas, and venting.

3 Installation

Installation describes how to install the Headspace Sampler. It includes instructions for unpacking the unit, checking the contents, connecting the power and gas supplies, making connections to an integrator or Agilent data system, and connecting the unit to a GC.

4 Running Checkout Samples

This chapter provides information on preparing and running the checkout sample to confirm that the sampler is operating correctly.

A Connecting a Swagelok Fitting

This appendix describes proper Swagelok connections.

It may come from a pressure-regulated purified source (see Figure 3 on page 27) or from the GC itself. A gas supply connection for vial pressurization is also required.

We recommend instrument or chromatographic purity grades specifically intended for chromatographic use. The gas purities in Table 2 are recommended for optimal chromatographic performance.

nnections

connection to a split/splitless inlet The sampler is ed between the inlet flow module and the inlet, allowing ethod control, via the GC, of flows and pressures for tent results between setups. The system is easy to ate and monitor but requires time to convert back to l inlet injection for nonheadspace samples.

connection to a volatiles interface The transfer line from mpler is connected to the volatiles interface. See the Cs user information for instructions.

onnections

connection to a split/splitless inlet The transfer line he sampler ends in a needle (part no. 2322590005) that is ed through the inlet septum. Conversion to normal on is rapid and simple.

connection to a cool on-column inlet The transfer line he sampler ends in a small od needle (part no. 90004) that is inserted through the inlet septum.
