PROCEDE D'INJECTION D'UN ECHANTILLON A ANALYSER DANS LE TUBE D'INJECTION D'UNE CELLULE DE MESURE, EN PARTICULIER D'UN DENSIMETRE

摘要

#CMT# #/CMT# The method involves fixing a standard disposable vertically closed syringe (1) and a consumable cap (6) on a support equipped with an injection device, and positioning the support at right of an injection post (12) of the injection device, so that a piston (3) of the syringe is situated next to a button (16) and the cap is situated next to the injection post. The syringe is displaced in a lower position, so that a punch perforates a membrane closure of the cap. The button is activated, so as to displace the piston of the syringe and inject a sample in the syringe in an injection tube. #CMT#USE : #/CMT# Method for injecting a sample to be analyzed in an injection tube of a measuring cell i.e. densitometer (claimed). #CMT#ADVANTAGE : #/CMT# The method enables injecting the sample to be analyzed in the injection tube of the measuring cell in an easy manner while filling the syringe from the container containing the sample to be analyzed and allowing introduction of the sample into the injection orifice of the injection tube of the measuring cell. The method allows analysis of the low viscosity and viscous samples without requiring after each measurement of complex rinsing steps involving utilization of large amounts of solvents. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side perspective view of an injection post of an injection device. 1 : Standard disposable vertically closed syringe 3 : Piston 6 : Consumable cap 12 : Injection post 16 : Button.
