Question

((((--Please type the answers because it is difficult to read different hand writings! )))) I just need part C. A- Why do we use electronic and computerized instrumentation in this laboratory, and not something less complex? B- In your own words, explain the main difficulty that arises with the use of electronic and computerized instrumentation. Why do you think it is important to acknowledge this difficulty? C- Again, in your own words, explain the two things you need to do in order to get good data when using computerized (or any other) instrumentation. D-The Motion Sensor works on the principle of echolocation. Describe how the sensor uses this to determine distances. Include the equation distance = speed time as part of your answer.

Answer 1

Ans: In computerized lab instrumentation different instrument may be developed by using different software systems this is the main difficulty that arises using electronic and computerised insrumentation. So, one should aware of that.

However, each instrument share share several primary characteristics. The parameters that effect instrument control, data acquisition, and data analysis are typically combined into what is referred to as a method. Methods can b e used repeatedly by setting up a sequence.

A sequence tells the instrument to inject samplel X, evaluate it using Method Y, and store the data in File Z.

Computers can store the operating parameters in an instrumental method which can be used repeatedly to evaluate samples, thus assuring reproducibility.
