Switching valve A is designed for
switching hydraulic paths for pressures up to 35 MPa, e.g. for switching columns without
stopping the flow of a mobile phase (without stopping a pump). According to the type of connection the valve may serve either for switching of up to six inlets to a single outlet, or for switching of up to six outlets to a single inlet. The standard accessories involve stainless steel through-screws and ferrules. |
Ordering No. 1003
Preparative injection valve B
 |
It makes possible injection of a larger amount
of a sample (of up to milliliters using an injection loop) to an uninterrupted flow of a
mobile phase, typically in preparative chromatography. A maximum pressure is 35 MPa. An injection system for the valve B and its holder is optional. The valve B may also be used as a switching valve 3 x 2. The standard accessories involve through-screws and stainless steel ferrules. |
Ordering No. 1005
Injection system for the valve B
- makes possible an injection using a LUER syringe.
Ordering No. 1015
Holder of an injection system for the valve B
It is designed for clamping the injection system to the valve B (please specify).
Ordering No. 1016
Analytical injection loop valve type C
 |
It may be used especially in HPLC to pressures
up to 35 MPa. Injected volume of a sample is given by a exchangeable loop used (3 to
200µl) fastened to the back of the valve. The loop should be filled using a Hamilton syringe with a needle for HPLC, or a LUER syringe with a needle supplied as an accessory. The supply also involve capillaries for waste, UNF through-screws and stainless steel ferrules. |
Ordering No. 1008
Analytical injection loop valve type D
It is a modification of the valve type C and has an additional switch, which makes possible to start an integrator, LCD 2084 detector software and LCP 4100 pump software, simultaneously with switching the valve to the INJECT position. A standard accessories involves a cable with a connector.
Ordering No. 1010
Injection loops
are designed for analytical injection valves types C and D, preparative injection valve type B, and Rheodyne valves (please specify the type).
 |
Allows injections to be made from up to 54 vials
placed in a in removable rotating carrousel. The autosampler is built-in a case of new series of ECOM instruments for HPLC and is controlled by microprocessor. The control and communication are performed through a keypad and a 2-line display, or through a PC by means of a bus.
|
Up to 250 steps, i.e. injections from individual vials, may be programmed with a possibility to repeat injections from one vials up to five times within a single step.
Up to 10 files may be stored in the unit memory. Files may be created, stored and edited. When the program is running it is possible to perform an injection from priority vial.
