LC-Pump SP 8800

INTRODUCTION

The SP8800 Series Pumps have been designed for ease of use and unsurpassed performance. They can be used as standalone pumps or as modules in a totally automated LC system. The SP8800 offers low pressure ternary mixing that provides accurate proportioning of binary or ternary mobile phase compositions in either the gradient or isocratic mode. The Isocratic SP8810 Pump offers all of the features and performance of the SP8800, except that the ternary proportioning valve, associated electronic circuitry and software are not included.

These pumps permit as many as 40 lines of programming in each of 10 method files, which are sufficient for even the most complex of gradient profiles.

Autosampler SP8880

INTRODUCTION

The Autosampler is a microprocessor-controlled modular automatic liquid sampling unit designed for use in liquid chromatography. It is designed to be part of a total System which includes a pump, a detector, and an integrator.

The Autosampler accommodates up to 81 samples, and up to 10 injections per sample in a completely automated operation. Interaction between the Autosampler and other Spectra-Physics instruments is available through the LABNETOO communications network.

SPECIFICATIONS

The Autosampler consists of a single microprocessor-controlled module, containing Keyboard and Display, the Injector Valve, Helium Degas control for flush solvent, diagnostics, and all required mechanical and electrical assemblies. Also included are a detachable flush reservoir, four sample trays, necessary tools, tubing and fittings for installation, and Operators Manual.

Capabilities include:

o    80 sample vials in four removable trays.

o    Vials are identified by the quadrant and the position in the tray.

o    Trays can be numbered 1 - 20 and automatically read.

o    A priority sample, position 5.01, can be run without disrupting the automatic sequence.

o    The Same vials can be used repetitively for calibration and re­calibration sequencing.

o    Full loop and variable volume injection (SP8880 only) modes.

o    Samples are withdrawn by a digital stepmotor-driven syringe through the concentric sampling needle which permits vial pressurization with a gas in full loop mode.

o    Automatic flush sequence after every injection.

o    Variable sample draw and injection dwell rates for the analysis of viscous samples.

o    Sample size, number of injections, run time and analysis file can be varied with each vial.

o    Injection Volume:

     Variable Injection mode (SP8880 only) - 1 microliter to 300 microliters in 1 microliter increments (1500 µL with optional 2.5 mL syringe).

     Fixed Loop mode - 20 microliter standard, 10, 50, 100, 200, and 500 microliter loops available.

o    Precision: 0.5% RSD at 10 µL for fixed loop mode and 1.0% RSD at 10 µL for variable volume mode. Precision values are based an a properly maintained instrument that is tested under the conditions stated in Appendix C.

o    Number of injections per vial: 1 to 10.

o    Minimum volume required: 5 microliters for a 1 microliter injection using an optional microvial (P/N 3115-0400).
