Semi-automatic headspace sampler

I. Overview

HLDK-S70seriesSemi-automatic headspace samplerIt is a product developed and launched by our company with a large touch screen display, compact structure, convenient human-computer interaction, and high quality at a low priceSemi-automatic headspace samplerIn order to ensure experimental consistency and simplify the process of inserting the sample needle by the experimenter, this product adopts an automatic injection needle insertion method, which only requires manual rotation of the injection disk.

3、 Main functions and features

1. Automatic injection needle: reduces manual operation and minimizes manual errors

2. Exquisite design: This instrument has been carefully designed with a simple and elegant appearance

3. Economic durability: The instrument components have undergone long-term testing and are stable and durable

4. Low residual adsorption: The entire pipeline is made of inert materials, and the entire pipeline is heated and insulated

5. Strong universality: It can be directly connected to any domestic or foreign instrument, making it easy and simple to use

6. Automatic six way valve: ensures consistent sample injection repetition

The combination of a six way valve and a quantitative ring effectively reduces dead volume and improves analytical sensitivity

8. The six way valve and transmission pipeline link have no transmission cold points, ensuring the integrity of the sample

9. The large touch screen interface has rich information, simple human-computer interaction, easy operation, and the following functions:

a) The information displayed on the LCD screen includes: multi method parameter settings, real-time working status, operation process information, etc

b) The headspace bottle, injection system, and sampling (injection) catheter are coordinated through a touch screen to achieve three-way heating and temperature control

c) 10 methods for editing, storing, and calling at any time

d)Can start synchronouslyGC、 The chromatographic data processing workstation can also be started by an external event program to achieve multiple repeated injections of the same sample bottle

e) Equipped with self checking function (board level and gas circuit) and fault display function

10. The sample transfer tube (including sampling needle) and injection valve have automatic blowback function, which avoids cross contamination of different samples
