Question

The minimum response time of mass spectroscopy is __________

(a) 15 secs

(b) 10 secs

(c) 5 secs

(d) 2 secs

This question was addressed to me in an interview for job.

The above asked question is from Instrumentation and Control in portion Instrumentation and Control of Fermentation Technology

Answer 1

The correct option is (c) 5 secs

To explain: The mass spectroscopy has the response time of fewer than 5 seconds for a full-scale response and taking about 12 seconds for a sample stream. It allows the monitoring of the partial pressure of gases.
