Topic: Ion Chromatography (IC)-1



科研儀器英語口語每日一練——離子色譜（一）

This is oral English of analytical instrument organized by EWG1990 English group. Welcome to lesson 7. Today the topic is the first part of the ion chromatography（IC）.

Now let's begin the part 1：

☞ Vocabularies:

1. 淋洗液 eluent
2. 保護(hù)柱  guard column
3. 分離柱 separation column
4. 污染物 contaminant
5. 離子交換 ion exchange
6. 抑制器 suppressor
7. 柱溫箱 column heater
8. 儲(chǔ)液罐  eluent reservoir
9. 漏液傳感器 leak sensor
10. 泵頭  pump head

Now let's begin the part 2：

☞ Sentences:

1. 研究了分離柱的選擇、淋洗液的濃度和流速對(duì)分離的影響。
The selection of columns, the effects of eluent concentration and the flow rate on their separation were studied.

2. 保護(hù)柱清除可能會(huì)損壞分離柱的污染物。
The guard column removes contaminants that might poison the separator column.

3. 離子交換和絡(luò)合反應(yīng)是土壤中常見的化學(xué)反應(yīng)。
Ion exchange and complexation reaction are the common chemical reactions observed in soil.

4. 洗脫液和樣品離子離開色譜柱后，經(jīng)過抑制器，該抑制器選擇性地增強(qiáng)樣品離子的檢測(cè)信號(hào)，同時(shí)抑制洗脫液的電導(dǎo)率。
After the eluent and sample ions leave the column, they flow through a suppressor that selectively enhances detection of the sample ions while suppressing the conductivity of the eluent.

5. 該系統(tǒng)通過PIC單片機(jī)對(duì)多路漏水傳感器信號(hào)進(jìn)行實(shí)時(shí)檢測(cè)與處理。
Using PIC single chip computer, the system can make real-time detection to multiplexer channel leak sensor signals.

This is the end of the class, see you tomorrow, have a great day!
