Gradient Valve provides an economical solution for upgrading an isocratic pump to a quaternary gradient pump. It includes a 4-channel gradient valve, a valve controller, and the control software.

It is designed to work with any HPLC pump that has a remote output. When working with an Agilent HPLC pump, it can also use dynamic data exchange for synchronization.

The installation is easy. The software will search for the valve and set computer communication parameters automatically.

LC-05 Auto Injector                                   More Information

• For automatic introduction of samples from a fixed source.

• Suitable for on-line monitoring and large scale purification.

•  Work with any type of HPLC instrument with easy integration.

• A valve-based fraction collector for large scale purification.

These low cost and high performance pumps have very small footprint and are easy to be accommodated into an existing HPLC. They can be used as secondary pump for 2D LC or on-line SPE. They can also be used to build an economical purification system by working with a LC-05 auto injector or a LC-04SP valve system.

• Compact design and small footprint (around 3 Kg)

• Dual plunger design for low pulse and continuous flow

• Inert wetting material: PEEK, stainless steel, Sapphire, Rubby, PTFE, PCTFE

• Controllable by LC-04SP software and easy integration with other HPLC

• Low cost upgrade to a quaternary pump

• Excellent flow accuracy (0.5%)

An on-line degasser helps to reduce detection noise and improve the retention time reproducibility. When a low pressure gradient pump is used, an on-line degasser is required for a smooth operation. PromoChrom offers 6 types of degassers to meet the needs from analytical scale to preparative scale HPLC.
