The Waters 626 LC system:
Is a High Performance Liquid Chromatography (HPLC) system for microbore, narrow bore, and analytical chromatography and micropurification
Uses 0.005- and 0.010-inch I.D. polyetheretherketone (PEEK) tubing to optimize system performance
Nonmetallic system construction allows you to use high-salt buffers and other aggressive mobile phases often used for separation of biological molecules
Performs complex methods with less eluent and in less time than semi-preparative systems

Dedicated keys provide direct access to all display screens. Cursor movement keys simplify programming, editing, and parameter entering. All keys are eluent-resistant. |
Programmable Timed Events |
You can program and store 15 timed events for each table. Contact closure switches S1 through S4 are located an the 600S controller rear panel for timed output to external devices. The following actions may also be controlled by timed events: Audible alarm Sparge rate Column temperature Proceed to initial conditions of specifed table Start run of specified table Turn detector lamp off |

Time- or Operator-Controllable Switch Closures |
Four controllable switch cosures to ground as follows: TTL-compatible terminals pulled up with 10-K ohm resistors to 5 V. May be pulled up to 12 V. Maximum allowable current = 1.0 A. Maximum allowable voltage = 12 V. Outputs may be controlled directly from keyboard or from events program. Two modes available from keyboard and Program Events screen: ON = switch closed to ground. OFF = switch open, +5 V to ground. Additional mode available from Program Events screen: Pulse = single contact closure to ground for 600 msec. |

Auxiliary Power Supply |
12 V to ground fused supply. 1 A max current. |
||||
Hold Output |
One TTL-compatible switch closure to ground. Maximum current sink: 100 mA. Low output indicates pumps stopped due to: Exceeding high-pressure limit Below low-pressure limit Abort input "Powerup" condition Used to communicate with Hold input on Waters 717plus autosamplers or other compatible input to prevent further injections. |
||||
Chart Output |
Two terminals (+,-) providing a 0 to 10 mV signal.This signal can be used to indicate the composition percentage of any one of the four eluents (%A, %B, %C, %D), the eluent flow rate (Flow), or the column temperature (Temp). |
||||
Pressure Output |
Two terminals (+,-) for recording pump pressure traces. 10 mV/6000 psi analog output; bypasses microprocessor. |
||||
Inject |
Receives a signal from an external injector (autosampler or manual injector) to initiate the chromatographic run. The Inject terminal also provides a signal to start a Waters 745B/746 Data Module (integrator). The Inject terminal accepts signals from several outputs, including TTL signals, open collector outputs, and contact closures. |
||||
Ground Terminals |
Connected to signal ground and used as reference for one of the following: Outputs (Hold, Inject and switches S1 to S4) Inputs (Inject and Abort) or 12 V power supply (not for use with 10 mV outputs) |
