[Product Name] GC2020 Hexanediamine Piperidine Analysis Gas Chromatography
【 Product Properties 】 Crystalline, boiling point 300 degrees
【 Analysis Principle 】 Gas chromatography is used to analyze hexamethylenediamine piperidine. Under selected working conditions, the sample dissolved in ethanol is vaporized and passed through a capillary chromatography column to separate the components, which are detected by a hydrogen flame ionization detector. Calculate the mass fraction of components using the normalization method based on the corrected area

Introduction to Instrument Features:
◆ Fully computerized button operation, 5.7-inch large LCD Chinese display, human-machine dialogue mode, easy operation ◆ Newly integrated digital electronic circuit, high control accuracy, stable and reliable performance, high-precision temperature control 50 times per second, accuracy up to 0.1 ℃.
Large column box volume: 300 * 280 * 180, accommodating multiple chromatography columns and two 100 meter 0.53 capillary columns to the maximum extent possible.
Introduce foreign sample inlet designs to address sample discrimination; The dual column compensation function not only solves the program drift caused by temperature rise, but also reduces the influence of background noise, resulting in a lower detection limit.
Intelligent rear door opening system, dual door design, infinitely variable air flow in and out, shortening the system's stable balance time after program temperature rise/fall; Heating furnace system: (temperature range) ambient temperature+5 ℃~400 ℃. The temperature equilibrium time of the heating furnace is determined by the user.
◆ Three injectors and three detectors can be installed simultaneously to solve complex sample analysis problems for customers.
◆ Better insulation effect: When the column box, vaporization, and detection are all at 300 degrees, the hottest spot on the outer box and top cover is only 40 degrees, which increases the experimental speed and ensures the safety of users.
◆ Optional installation of automatic/manual six way injection valve, headspace sampler, thermal analysis sampler, cracking furnace, methane conversion furnace and other extension devices can be added to facilitate the analysis of special samples.
◆ It has a power on self-test function, fault display, automatic protection, instant power-off protection, and strong anti-interference ability.
Excellent design concept:
◆ Vaporization chamber design *, with smaller dead volume;
◆ Easy replacement of accessories: the injection pad, liner, polarizing electrode, collection electrode, and nozzle can all be replaced with one hand;
◆ Easy replacement of the main body: The filling column, capillary sampler, TCD, FID detector can be disassembled with just one wrench, making maintenance very convenient;
◆ Excellent nozzle: * High temperature resistant quartz design, less prone to breakage and better inertness, rotating seal, better sealing * ◆ Reasonable positioning: * Capillary positioning system, effectively ensuring column installation repeatability and constant combustion rate;
◆ Column head injection: Fill the column head injection to effectively prevent diversion discrimination effects.
