The following illustrations and descriptions refer to the instrument model and are drawn from brochures. They do not represent the scope of delivery. Please refer to the text of the offer for the exact scope of delivery.
The Waters 2790 Separations Module integrates a solvent management system and a three-axis Sample management system to provide high-throughput analysis for HPLC, LC/MS, or flow injection-mass spectrometry applications.
Components
The 2790 Separations Module consists of:
Three-axis (XYZ) sample management system
HPLC solvent delivery system
Four-channel inline vacuum degasser (one channel reserved for sample management purge solvent)
Integral plunger seal-wash system
LCD display
Keyboard
Floppy dick drive (using 3.5-inch floppy disks)
Column heater (optional)
Sample heater/cooler (optional)
Column selection valve (optional)
Bar code reader (optional)
When the 2790 Separations Module with the optional sample heater/cooler is installed with the 2790 column heater, it is known as the 2790XE. Refer to Section B.3, 2790 Module Options, for Information about the 2790 Separations Module options.
Operating Modes
The 2790 Separations Module can operate as a stand-alone HPLC system controller, as an HPLC system controlled by Millennium@ 32 software, or as a component of an HPLC or LC/MS system controlled by MassLynx" software.
As a stand-alone HPLC system controller, the 2790 managen a variety of sample plates while controlling one or morc detectors. Optionally, the 2790 can also control a 3-column selection, 6-column selection, or column regeneration valve.
As an HPLC system controlled by Millennium32 software (version 3.2 or higher), the 2790performs sample and solvent management, column selection, and system equilibration.
As a component of an LC/MS system controlled by MassLynx (version 3.3 or higher), the 2790 performs sample and solvent management, column selection, and system equilibration.
An LC/MS system that includes the 2790, the Waters ZMD mass spectrometer, and MassLynx software is designated a Waters Alliance® HT LC/MS System (Figure 1-2).
System Configurations
The 2790 Separations Module supports IEEE-488 and I/0 connections within a variety of HPLC and LC/MS system configurations.
The 2790 Separations Module can be configured in a stand-alone mode to provide control of up to three UV or RI detector channels as follows:
Up to two UV detector channels (a Waters 2487 Dual Detector, single or dual-channel, and/or a Waters 486 Tunable Absorbance Detector)
One RI detector channel (Waters 2410 or 410 Differential Refractometer).
The 2790 Separations Module can be configured under Millennium32 software. You use a Millennium32 Chromatography Manager workstation to create methods, which control the Separations Module and other HPLC system components. All detectors that are supported by Millennium32 software can be used wich the 2790 Separations Module. Data from the detectors are sent over the IEEE-488 Interface bus to the Millennium32 software for processing.
In an Alliance HT LC/MS system controlled by MassLynx software, MassLynx can control up to two of the following (one of each):
Waters ZMD detector
Waters 2487 detector
Waters 996 detector
Micromassa single- or triple-quadrupole or time-of-flight mass spectrometer
Waters SAT/IN" Module
Parameter Control
In a stand-alone HPLC System, the 2790 Separations Module can control:
Method programming
Solvent composition
Flow rate
Plunger seal-wash flow
Sample injection
External events
Advanced sample management functions including:
Rapid equilibration
Parallel sample processing
Sample pooling
Operation of detectors over the IEEE-488 Interface bus
Inline degassing
Column heating (optional)
Sample heating/cooling (optional)
Bar-code reading of sample plates (optional)
With the 2790 Separations Module, you can make parameters such as pressure limits or syringe
draw rates pari of a Separation method. You can program the values of these parameters to change from method to method without having to Set up the Instrument before each run.
Spill Protection
All fluid-handling areas of the 2790 haue spill protection; spilled solvent is routed to waste line connectors below the front panel. A drip tray is provided for the top cover if you place a detector an top of the 2790. A solvent bottle tray provides storage for up to four 1 -L solvent reservoirs.
Methods Storage and Retrieval
You can Store up to 60 methods (methods include separation methods and sample sets) in the 2790. When the number of stored methods approaches the maximum (60), the delay when you create and saue methods increases to more than 30 seconds. When 60 methods haue been stored, a warning message appears indicating that storage capacity has been reached.
The 2790 can export and import separation methods and sample sets from Standard PC-formatted, 3.5-inch floppy disks using the built-in floppy disk drive.
The 2790 also Supports import of sample sets created and exported using a PC-based Spreadsheet application or text editor in ASCII Format.
Record-Keeping Functions
The 2790 automatically records:
Total number of injections
Total solvent usage (pumped through the System)
System errors
Programmed operating conditions for each run
Column selection This information can be:
Printed using a connected serial printer
Transferred to an external device, such as the Waters 746 Data Module
Exported to a 3.5-inch floppy disk as an ASCII Eile
Sample Heater/Cooler
The 2790 can be shipped with the optional sample heater/cooler that maintains the sample compartment at temperatures from 4 to 40 °C. The sample heater/cooler is factory-installed on the 2790XE.
Column Heater
The 2790 Column Heater maintains the column at temperatures from 5 °C above ambient (minimum of 20 °C) to 60 °C. You can enable an alarm to warn you if the temperature varies outside the range you specify. The procedure to install the column heater is described in Section 2.3, Installing the Column Heater. The 2790XE includes the column heater.
The 2790 Column Heater is shipped with either no valve or with one of three optional column-selection valves and the associated tubing and connectors. See Section 1.4, Options and Accessories, for information on the column selection valves used with the 2790.
For more information on column heater options, sec Section B.3, 2790 Module Options.

2700 Sample Manager
The Waters 8 2700 Sample Manager is a high-capacity sample processing system for the management of sample injection in high-performance liquid chromatography (HPLC), liquid chromatographymass spectrometry (LCMS), or flow injection into a mass spectrometer. The 2700 Sample Manager automates sample aspiration and injection from microtiter plates, test tubes, Eppendorf tubes, or conventional autosampler vials. When the available options are installed, the instrument can provide single-point management of sample pretreatment, column selection, injection, and collection of separated fractions. Figure 1-1 shows the major parts of the instrument.
The 2700 Sample Manager can function as a component of a single Millennium 8 Software-based HPLC system or as part of one system in a multisystem Millennium chromatography Manager configuration.
The 2700 Sample Manager is controlled by software installed an a computer that is running Windows 3. 1, Windows 95 -, or Windows NT". The control software may be operated independently or with a DDE link to Waters Millennium Chromatography Manager (version 2.15.n) that is running Windows 3.1. The 2700 Sample Manager connects to the computer through an RS-232 post and triggers Operation of an HPLC module by transistor-to-transistor logic (TTL).

PL-ELS 1000
Introduction
The PL-ELS 1000 evaporative light scattering detector or mass detector is a unique and highly sensitive detector for non-volatile solutes in a volatile liquid stream. lt is mainly used as a concentration detector in Gel Permeation Chromatography (GPC) and other forms of Liquid Chromatography. The solvent stream containing the solute material is nebulized and carried by a gas flow through an evaporating chamber. The solvent is volatilised, leaving a miss of solute particles that scatter light to a photosensitive device. The Signal is amplified and a voltage output results. The output is directly related to the "mass" of the solute particles passing through the light, hence the narre "Mass Detector".
The PL-ELS 1000 may be used alone, or as one of several detectors in a GPC or Liquid Chromatography System. As the solvent or eluent is evaporated in the course of the analysis, the PL-ELS 1000 must be the last in series if used in conjunction wich other detectors. If the PLELS 1000 is being used as the last detector in a series, care must be taken not to exceed the recommended back-pressure in detector cells in other units.
