System Description
The Waters™ 2690 Separations Module (Figure 1-1) is an integrated solvent and sample
management platform. This integration of two traditional high performance liquid
chromatography (HPLC) components streamlines all critical separation functions.
The sample management system in the Waters 2690 Separations Module uses five
carousels with a total capacity of 120 vials. A carrier rotates the carousels to the injection
station in the sample compart men t.
The Waters 2690 Separations Module is available from Waters in a number of
configurations, differing from each other by the options that are included.
The two primary configurations are designated:
2690
•
helium sparge for solvent conditioning, integral plunger seal-wash system, 120-vial
capacity sample management system, liquid-crystal display and keyboard user
interface, and floppy disk drive.
2690 XE
•
sparge system with a four-channel in-line vacuum degasser , and adds a column
heater and a sample heater/cooler.

Preparing the Se parations
Module for Operation
Before you can prepare the Separations Module for operation, you need to power on the
2690 Separations Module by moving the power switch (located at the top of the left side
panel) to the I (On) position. The startup diagnostics routine begins.
2.1 Powering On
Startup Diagnostics
The startup diagnos tics routine performs the following functions and tests:
• CPU board
• Memory (RAM and ROM)
• Keypad
•Display
• External communicat ion
• Digital signal processor (DSP)
• Floppy disk drive
Once the electronic part of the diagnostics test is complete, the front-panel screen
displays the results of the tests, as shown in Figure 2-1

Programming for Auto Shutdown
You can set up the Separations Module to shut down automatically after a specified period
of inactivity. Inactivity is defined as:
• No keyboard use
• No injections performed
14Preparing the Sepa rations Module for Operation
Page 15
• No changes sent to the Separations Module from a remotely connected Millennium
Chromatography Manager workstation, MassLynx computer, or external
autosampler
• An error condition that suspends the operation of the Separations Module
You can leave the Separations Module in the shutdown state indefinitely. The separation
method you specify in the Auto Shutdown dialog box defines the initial conditions that are
applied after the specified period of inactivity. Use the auto shutdown function:
• When there is a long delay between injections
• To minimize solvent flow after an unattended or long run
• To minim ize sparge gas consumption
• To disable the vacuum degasser
• To disable temperature controls
• To turn off detector lamps

all the air through the solvent line into the syringe.
9. Repeat steps 7 and 8 for each solvent line you want to prime, then close the
prime/vent valve.
10. Press a screen key corresponding to the solvent line with which you want to

lowest viscosity to help purge air from the lines, especially if the in-line vacuum
degasser is installed.

Perform a wet prime when you want to change reservoirs or solvents, or if the Separations
Module has been idle for some time. The wet prime replaces solvent in the path from the
reservoirs to V3 (waste). If the solvent lines are dry, perform the dry prime procedure
before continuing.
Attention:
To av oi d precipitating salts in the Separations Module, use an intermediate
solvent such as water when you change from buffers to high-organic-content solvents.

For rev ersed-phase HPLC applications, use an aqueous plunger seal-wash solution with
enough organic content to inhibit bacterial growth. For example, use an 80%water:20%
methanol solution or an 80% water:20% acetonitrile solution, depending on your
application. For GPC separations, use a 50% methanol:50% water seal wash solution. If
required, use an intermediate solution to prevent immiscibility or precipitate problems
when you switch between GPC and reversed-phase analytical solvents.

Recommended Preparation
Procedures
This chapter outlines the steps to prepare both degasser and sparge-based 2690
Separations Modules for operation using Waters-recommended procedures. Flow charts
provide the sequence of steps to prime, equilibrate, and purge a Separations Module that
is in one of the following states:
• A new or dry Separations Module
• A Separations Module that has been turned of f or left idle with no flow
• A Separations Module that requires a solvent change, such as from a buffered
solvent to an organic solvent
For step-by-step instructions on how to use Direct Functions to prime, equilibrate, and
purge your Separations Module, refer to the
, Chapter 4, Section 4.4, Performing Direct Functions.

To maximize degasser efficiency (and fill all four degasser chambers with solvent), Waters recommends that
all four solvent reservoirs be filled (even if four solvents are not used). If you choose water as one of the
“unused” solvents, change the water weekly to prevent bacterial contamination.

Except for the short period of time required to equilibrate solvents in the degasser, do not run the degass er
without solvent flow. Refer to the “Degasser Considerations” discussion, Section 1.5, for more details.
