Methodology

NOTE: The system arrives with a CD containing factory test method and data
files. Use these method files to do the sensitivity tests and retain the test files CD
for your records.

1. Ensure the MS temperatures for this acquisition are set as follows:

•

Trap: 150 °C

•

Manifold: 40 °C

•

Transfer Line: 230 °C

2. In System Control, activate the

CI MEOH Test

method from the Service

Folder.

Acquiring BZP

1. Use the Inject Single Sample option to make a 1µL manual injection of test

mix, part number 393065201.

2. Use a lower air gap to avoid sample loss through the tip of the needle.

3. Ensure the syringe plunger is not forced out of the syringe barrel if a

Pressure Pulse is used in the method.

4. Ensure the split valve has changed from open to close before injecting by

striking the injector auto-start switch with the syringe barrel before
depressing the syringe plunger.

5. Inject slowly (1µL/sec) to avoid sample loss through explosive vaporization.
