Problems solved by technology

[0003] Intrinsically safe gas chromatograph is a brand-new gas analysis equipment, and its safety performance has been unanimously recognized by users. In order to meet the intrinsic safety requirements of gas chromatograph, the instrument has a larger gas circuit and circuit than conventional instruments. However, the current installation and use methods of intrinsically safe gas chromatographs follow the conventional gas chromatographs, which is inconvenient for installation and application.

Embodiment 1

[0026] Such as Figure 1-Figure 4 As shown, the present invention provides a method for installing and using an intrinsically safe gas chromatograph. The upper casing 104 and the lower casing 102 are separated for easy installation. The circuit and gas circuit interface are on different panels, so that the gas circuit and circuit wiring are regular and do not interfere with each other; the function of checking the power, starting and shutting down with one key is realized.

[0027] Such as figure 1 As shown, an intrinsically safe gas chromatograph includes an upper housing 104 on the lower housing 102, a battery rack 402 for installing a battery 401 inside the lower housing 102, an intrinsically safe chromatographic module 101, a gas injection pump 103, and a lower housing 102. The side of 102 is provided with network interface 201, data transmission interface 202, backup interface 203, sample gas inlet 204, carrier gas inlet 205, exhaust port one 206, exhaust port two 207, g...

Embodiment 2

[0033]A method for using an intrinsically safe gas chromatograph, using the intrinsically safe gas chromatograph as in embodiment 1, comprises the steps:

[0034] Step 1. Press and hold the switch 405 for a certain period of time (1-3 seconds), and the display screen 404 will display "power on" and the remaining power of the battery 401. If the remaining power is less than a fixed value (10%), keep pressing the switch 405 until the display screen After 404 is in the “off” state, release the switch 405 to charge through the charging interface 406 .

[0035] Step 2. If the remaining power is greater than the fixed value (10%), keep pressing the switch 405, and the display screen 404 will display "standby", indicating that the intrinsically safe chromatograph can perform gas analysis.

[0036] Step 3. Insert the analysis gas sample into the sample gas inlet 204 for gas analysis.

[0037] Step 4. After the use is completed, press and hold the switch 405 button, and release the bu...

Abstract

The invention belongs to the field of gas chromatographs, and is specifically an intrinsically safe gas chromatograph, wherein a battery rack for installing batteries, an intrinsically safe chromatographic module and a gas injection pump are arranged in the lower casing, and a network interface, a data transmission interface, and a gas injection pump are arranged on the side of the lower casing. Spare interface, sample gas inlet, carrier gas inlet, exhaust port 1, exhaust port 2 and gas injection pump exhaust port, power management board is installed in the upper shell, and the top surface of the upper shell has a display screen, switch, charging interface and One-button control circuit; switch, display screen, and charging interface are all electrically connected to the power management board, electrical equipment is electrically connected to the battery, the network interface, data transmission interface is connected to the signal of the intrinsically safe chromatographic module, and the carrier gas inlet and sample gas inlet and other interfaces are connected with the intrinsically safe chromatographic module through pipelines. In terms of installation and use, the one-key switch and standby functions are realized through the one-key control circuit. The gas circuit and circuit wiring are regular and do not interfere with each other. The invention also provides the use method of the chromatograph.

Description

technical field [0001] The invention belongs to the field of gas chromatographs, and in particular relates to an installation and use method of an intrinsically safe gas chromatograph. Background technique [0002] Gas chromatography has the advantages of high separation efficiency, fast analysis speed, high detection sensitivity, good selectivity, and simultaneous analysis of multiple components. It is widely used in medicine and health, petrochemical, environmental monitoring, and coal mine safety. As a gas chromatograph with the highest safety performance, the intrinsically safe gas chromatograph plays an important role in safe production. [0003] Intrinsically safe gas chromatograph is a brand-new gas analysis equipment, and its safety performance has been unanimously recognized by users. In order to meet the intrinsic safety requirements of gas chromatograph, the instrument has a larger gas circuit and circuit than conventional instruments. However, the current instal...
