What is separation module?
Separation module (optional) The Separation module optimises the recovery of hydrocarbons to close to 100% by means of Liquid/Solid (decanter) and Liquid/Liquid separation (high speed separator). Alternatively a Solid/Liquid/Liquid separation module can be used (three-phased decanter).
Why is methanol used in HPLC?
Methanol has superior solubility properties compared to other popular HPLC solvents (better than ACN). Flushing a system down for several hours seems excessive.
Why is purging important in HPLC?
Answer: “When setting up an HPLC system, the aim of the purge is simply to flush through all the lines so that any remaining solvent in them from a previous analysis or wash is replaced with the new mobile phase. As you would expect, the amount of new solvent required depends on the volume of the tubing in the system.
What is Loop in HPLC?
The injection loop is a critical component of an HPLC and is potentially one of the largest sources of excess HPLC system volume. The sample is injected into the loop while the loop is switched out of the HPLC flow path.

How do I update the firmware on my waters e2695 system?
Ensure the e2695 is connected to the workstation or the network switch that’s dedicated for the e2695 system. Note: Use a straight-through Ethernet cable to connect the e2695 to the workstation or network switch. 3. Insert the Waters e2695 Firmware Update DVD into the workstation’s DVD drive.
What is the Alliance e2695 module?
Separations module overview The Alliance e2695 Separations Module is an integrated solvent and sample management platform. Integrating the two, traditional high performance liquid chromatography (HPLC) components—a solvent management system and a sample management system—facilitates all critical separations functions.
How much clearance should be provided at the rear of e2695?
Caution: To avoid overheating the separations module, provide at least 16 cm (6 inches) of clearance at the rear of the separations module. 2 Install the e2695 Separations Module 48 July 29, 2013, 715003794 Rev. B
