Helium ionization gas chromatography
Thread Content
For helium ionization gas chromatography used in producing high-purity gases, are domestic products better or imported ones? Have you used the chromatographs produced by Shanghai Huaai Chromatography Analysis Co., Ltd.?
At present, domestic instruments are developing at a decent pace, but there is still generally a greater trust in imported ones. Imported instruments are often chosen when conditions permit.
There is no objective standard for determining whether chromatography is good or not. Is it of excellent performance? Is it fully configured? Is it easy to operate? Is the data accurate? Is it fast in analysis? Is it cheap? Is the service timely? Are there ample spare parts? Is it the leader’s approval? Is it the high kickback? Is the relationship between purchasing and sales good? Is the small gift given during the instrument exchange valuable? Are the salespeople taking users out for expensive meals? Is it great entertainment after a meal? ………… The original poster needs to come up with a standard for judging quality in order to make comparisons.
This reply should be the best answer to similar questions: lol It seems that each of the points mentioned is important and cannot be ignored. Hearing these words is truly like gaining the knowledge of ten years of study.
For quality inspection personnel, the key criteria for determining whether something is good are instrument stability, good repeatability, and the ability to operate stably over long periods of time. Softness refers to after-sales service – the ability to receive timely and high-quality after-sales support; everything else has nothing to do with the inspectors.
Imported instruments generally have fast analysis speeds, excellent performance, stability, good repeatability, and the ability to operate stably over long periods of time. One downside is the high price. Most analytical testers like it. Irrelevant bribes, when given in large amounts, make things easier for managers; yet the quality of domestic products still falls short – they’re of poor quality, and no one can tolerate that.
When it comes to helium ionization gas chromatography for high-purity gases, it’s difficult to decide whether domestic or imported versions are better. I would say imported ones are better as they are more durable, but your supervisor says they are too expensive, so it’s better to opt for domestic products. I say that domestic products offer good value for money, while your boss prefers imported ones as they are more reliable. It really depends on your needs to decide.
