When you choose filter as collection medium for airborne particulate sampling at a work place, what factors should be considered in your decision making? (10%) 3. Why the direction setting of sampling probe for airborne particulate sampling is important? (10%) 4. Name three common methods for airborne particulate sample analysis, in terms of method name, item/material(s) being analyzed, and brief principle for the instrument operation. (10%) 5. Please briefly describe the major methods for gas or vapor samples collection in the working environment. Name an example for each type of these methods and describe each one's strength and weakness. (10%) 6. Please briefly describe the design for adsorbent tube. What are the major factors of concern for the collection efficiency of granular adsorbents? How do they affect the sampling capacity? And please name three different types of adsorbent, and three corresponding compounds that could be sampled with these respective adsorbent. Also, please define "breakthrough". (20%) 7. What are the major characteristics of passive sampling? What is the fundamental theory ir works with and what factors may interfere with it? (10%) 8. What are the commons and differences between gas chromatography(GC) and high performance liquid chromatography(HPLC)? Please name at least one type of detector that may be linked with GC or HPLC, respectively, and briefly describe how they work for chemical determination? (10%) 9. Please draw the layouts and components of a sampling train to illustrate the calibration for gas/vapor sampling? (10%) 10. (a) (5%) In the following figure, one impinger containing sampling solution is linked with a tube to an empty impinger, which is consecutively to drawing pump. What is the dual-impinger device for? (b) As shown in the following figure, what mechanism is applied for such a device for airborne gas sampling? (圖略) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.213.241
