SAMPLE INJECTOR, SAMPLE INJECTING METHOD AND LIQUID CHROMATOGRAPHY EQUIPMENT

摘要

The present invention is a sample injector, a sample injection method of controlling the flow of the mobile phase using a switching valve , and relates to a liquid chromatography device , and a port connected to a column for separation , and a pump for supplying a mobile phase , and one pair of the sample for injection needle , a syringe , a needle for the sample injection and optionally to either the pump or syringe in addition, along with connection , a valve needle to the sample injection and the other to the pump . And , by operating the valve , the connection to the sample injection needle when the sample injection needle is attached to the port for the pump . In addition , when the needle for the sample injection port and the other attached to a junction box for the sample injection needle to the syringe and the needle as well as for sample injection and the other is configured to connect to the pump .
