T-type gas chromatograph

Product Introduction

As an entry-level model with fool like operation and simple configuration scheme, it is deeply loved by conventional laboratories such as Baijiu, vegetable oil enterprises, medical equipment enterprises, fire extinguisher enterprises, pesticide chemical enterprises, etc. For beginners of chromatograph, it is a simple learning machine, easy to learn and understand. The instrument adopts a high-definition touch screen, stable voltage and current control flow path, analog circuit, and belongs to the single detector model.

1. This model has added a fully tempered glass touch screen LCD display, which is sturdy, durable, and sensitive to touch. Tempered glass is more corrosion-resistant,

Solved the problem of traditional LED touch displays in gas chromatographs being insensitive to touch due to exposure to organic solvents in corrosive environments for a long time.

2. High sensitivity FID detector: realizes automatic ignition and shutdown monitoring of FID, without manual triggering, automatically controls the ignition frequency according to temperature, and can set the ignition threshold arbitrarily. A highly stable FID detector is suitable for trace component analysis, with a simple structure and low maintenance costs. The detector contains a quartz nozzle with a smooth outer wall, which is not prone to carbon deposition and has a long service life.

3. Advanced capillary injection system: The injection port is made of 316L stainless steel material, which optimizes the structure of the injection port. The size of the injection spacer is further optimized, and imported spacers can be directly used for complex samples.

4. Both quartz liner and liner O-ring can use imported products to ensure no ghost peaks during injection.

5. Accurate automatic rear door cooling system; The entry-level chromatography also has a precise automatic back door cooling system, which still performs well in near room temperature operation. The double door design is still classic, and the software provides precise data analysis, solving the unstable situation of old-fashioned travel switches and infrared switches, making stability higher.
