INJECTORS
Either one or both of the following injectors should have the facility for manual injection even if auto-sampler/Head space/online GSV are present
1. SPLIT / SPLIT LESS INJECTOR
Injector should be suitable for all capillary columns.
Higher split ratio (0-7500 or better)
EPC for two pressure ranges (0-100 psi with adjustments in 0.001 psi and 0-150 psi with adjustments in 0.001 psi)
Gas saver mode to reduce gas consumption

2. PTV INJECTOR
Quoted system should provide the flexibility of a standard split/split less inlet, combined with temperature programmable capabilities which allow for large volume injection. Injector must also support cool injections for improved signal strength. Temperature control should be with liquid CO2 facility. Injector should have Electronic Flow control with 0.001 mL/min accuracy or equivalent facility.
Pressure range: 0 - 100 psi or better
Maximum temperature: 400 Deg C or better
Split ratio setting range: 0 – 7500 or better

BACK FLUSHING
System must be quoted with software controlled back flushing facility with displays for positive and negative flows and settable inlet / outlet pressures.
