You used a flame ionization detector(fid) in this experiment.
(a) explain how a fid detector works.
(b) another common detector for gc is a thermal conductivity detector (tcd). describe how a tcd works.
(c) both the fid and the tcd are classified as "bulk" detectors. what does this mean?
(d) what are the advantages and disadvantages of a fid and a tcd?

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s

Ascientific blank must be testable and capable of being proven false?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
