1、 On demand procurement is economical and practicalThe quality of the second-hand chromatograph is good

regardingSecond hand chromatographFor procurement, first of all, you should understand the following questions: Are you doing quantitative analysis or research? What kind of samples are you making? What substance should be analyzed in the sample? What is the content range? Financial situation? After knowing the above content, you can request product samples, user manuals, or log in to the manufacturer to learn more about the performance characteristics and technical indicators of each manufacturer's instrument.

2、 Principles for selecting domestic gas chromatograph manufacturers: pay attention to quality controlThe quality of the second-hand chromatograph is good

Stable and reliable; Moderate price; Easy to operate; Beautiful appearance; Maintenance support; Convenient service; Long lifespan; Low cost.

3、 The old instruments provided by the company are assembled with some old accessories, not second-hand chromatographs that some companies have phased out. They can ensure normal use, update accessories in a timely manner, and facilitate timely repair and maintenance in case of instrument failure.

Instrument configuration: single FID+capillary injection system or TCD+packed column injection system, five stage lift, intelligent back door; (Chromatographic workstation+chromatographic analysis column=brand new); The company provides analysis solutions, instrument configuration, and usage guidance
