Topic: Ion Chromatography (IC)-1



科研仪器英语口语每日一练——离子色谱（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. 保护柱  guard column
3. 分离柱 separation column
4. 污染物 contaminant
5. 离子交换 ion exchange
6. 抑制器 suppressor
7. 柱温箱 column heater
8. 储液罐  eluent reservoir
9. 漏液传感器 leak sensor
10. 泵头  pump head

Now let's begin the part 2：

☞ Sentences:

1. 研究了分离柱的选择、淋洗液的浓度和流速对分离的影响。
The selection of columns, the effects of eluent concentration and the flow rate on their separation were studied.

2. 保护柱清除可能会损坏分离柱的污染物。
The guard column removes contaminants that might poison the separator column.

3. 离子交换和络合反应是土壤中常见的化学反应。
Ion exchange and complexation reaction are the common chemical reactions observed in soil.

4. 洗脱液和样品离子离开色谱柱后，经过抑制器，该抑制器选择性地增强样品离子的检测信号，同时抑制洗脱液的电导率。
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. 该系统通过PIC单片机对多路漏水传感器信号进行实时检测与处理。
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!
