BG49130A1 - Device for indroduction of liquid samples into systems of measuring in flood - Google Patents

Abstract

The device is applied in the atomic-absorption analysis, the emission spectral analysis, etc.; in incoming and outgoing analytical control of raw materials and products from the chemical industry and metallurgy, in geological explorations, clinical analyses, protection of environment, etc. It has a low dead volume, dilution of tested sample and duration of analysis. The device is simple and does not require specific skills on the part of the operator. It is easily automated. It consists of a peristaltic pump (1) with a cycle engine. The inlet of the pump (1) is connected to a capillary (2) submerged in a vessel (A) with a solution-bearer of the tested sample. The outlet of the peristaltic pump (1) is connected via a three-branch offshoot (3) with a pulveriser of the measurement system, while the three-branch offshoot (3) is connected with a dosage capillary (4) for dosing the sample directly into the pulveriser of the measurement system through consecutive submerging of the capillary in a vessel with a solution of the tested sample and in another vessel (B) with a solution-bearer of the sample.<IMAGE>
