Topic: High-Performance Liquid Chromatography (HPLC)-3



科研儀器英語(yǔ)口語(yǔ)每日一練——液相色譜（三）

This is oral English of analytical instrument organized by EWG1990 English group. Welcome to lesson 6. Today we will cover the third and final part of High-Performance Liquid Chromatography（HPLC）.

Now let's begin the part 1：

☞ Vocabularies:

1. 響應(yīng)時(shí)間 relative response
2. 校正因子 correction factor
3. 相似相溶原則 rule of similarity
4. 最小檢測(cè)濃度 minimum detectable concentration
5. 外標(biāo)法 external standard method
6. 噪信比 noise-signal ratio
7. 峰寬 peak width
8. 物理鈍化法 physical deactivation
9. 校正曲線法 calibration curve method
10. 體積排阻色譜 size exclusion chromatography
11. 內(nèi)標(biāo)法 internal standard method
12. 二極管陣列檢測(cè)器 diode-array detector，DAD
13. 標(biāo)準(zhǔn)偏差 standard deviation

Now let's begin the part 2：

☞ Sentences:

1. 內(nèi)標(biāo)法和外標(biāo)法可用于對(duì)啤酒中的不揮發(fā)組分進(jìn)行定量檢測(cè)分析。
Quantitation analysis of involatile compositions in beer could be done by internal standard method or by external standard method.

2. 建議采用校正曲線法測(cè)定HNIW純度。
It is prefer to use calibration curve method to analyze purity of HNIW.

3. 那么，如果重復(fù)執(zhí)行度量過(guò)程，平均值和標(biāo)準(zhǔn)偏差會(huì)有多大變化？
Then how different would the mean and standard deviation be if the procedure were repeated?

4. 對(duì)于信號(hào)處理來(lái)說(shuō)，其中一種方法是對(duì)信號(hào)的濾波，即在接收到的信號(hào)中提取有用的信息，提高信噪比。
To signal processing, one of the methods is signal-filter, that is, distilling useful information from the signal that received to enhance the signal-noise ratio.

5. 文中對(duì)儀器裝置、色譜條件、樣品處理、干擾物的消除、最小檢測(cè)濃度、重復(fù)性、方法應(yīng)用等進(jìn)行了報(bào)導(dǎo)。
Instrumental installation, column, conditions, sample disposal, interfering component elimination, minimum detectable concentration, repeatability and applications of the method were reported.

This is the end of the class, and I wish you a nice day!
