This has to start from the naming rules of the instrument. Why can't gas chromatography mass spectrometry be called mass spectrometry gas chromatography? Why can't flow injection inductively coupled plasma mass spectrometry be abbreviated as ICP-FI-MS?

In general, the naming order of the instrument should be strictly consistent with the order of the analyte experienced during sample analysis, especially when there are many combined techniques for sample processing, such as ID-FI-IC-ICP-TOF- MS means isotope dilution-flow injection-ion chromatography separation-inductively coupled plasma-time-of-flight mass spectrometry. For a specific instrument, such as ICP-AES, is it called an inductively coupled plasma atomic emission spectrometer or an inductively coupled plasma atomic emission spectrometer? From the above analysis, we can see whether it is a "meter" or a "meter" "They are all at the end of the instrument name and should correspond to the analyte detector.

Generally speaking, "meter" means that the signal of the analyte has been directly converted into an electrical signal at the end of the analytical instrument, which corresponds to the "meter" in English, such as a light meter; while the signal of the analyte has not been directly converted An instrument that is an electrical signal is represented by an "instrument". Corresponding to the "scope" in English, the detector is usually a photosensitive plate, and what you see directly with your eyes is called a "mirror", such as a microscope or an electron microscope.

With the widespread use of computers, more and more instruments directly output analog or digital electrical signals. According to this understanding, it seems that most of them should use "meters". In fact, it is not the case, because the Chinese have another understanding. Generally speaking, smaller instruments are represented by "meters", such as thermometers and pH meters, while large analytical instruments are represented by "instruments" and "spectrometers" (Puyi ? Anyway, he is also an emperor, of course, very big). In this way, most instruments are mostly expressed by "instruments".

Regardless of whether you use "meter" or "instrument", in Chinese, if there is no uniform, you can use whichever one speaks smoothly, but in English, it is generally agreed to use "meter" or "scope", it is best Don't use it wrong.

Coffee Storage Shelf

Coffee has been integrated into modern life. Coffee is not only a drink, but also a wise friend who can talk about his feelings. Pick up the coffee cup, taste the taste of coffee itself, and carry a big dream in his heart. Like all of us, we also have the habit of drinking coffee. We like the unique and rich aroma of coffee beans and the spiritual stimulation of coffee, which can make me concentrate on my work. I have always used the coffee capsule machine, but I always have a problem. I don't know where to throw all kinds of coffee capsules, which makes the house messy. Sometimes I have to turn the boxes and cabinets when I want to drink coffee, Look everywhere for the coffee capsules you bought. Recently, I started the coffee storage rack, which completely solved my problem. The coffee capsule bracket can store the coffee capsule well. It doesn't need any complicated operations when it is used at ordinary times. It can be used only by people who go there. It really saves a lot of time for everyone. The narrow shelf won't occupy too many places. This is the designer's perfect use of high space.
