Because you are asking for information to help get around detection of illegal activity, we can not answer this question, except to say:
The best and surest method for passing a drug test is not to take illegal drugs.
Some drug tests will spot it, but if you have a current prescription, and bring in proof, it will not count as a "positive" for most purposes, including job-seeking. If you are not supposed to be taking it, you could have a problem on some drug tests but not others. Sorry, I don't know which methods will detect it and which ones won't.
Some athletes have taken drug tests to prove they are not on steroids.

Some methods of trapping carbon dioxide are: electrochemical reduction, cooling it into a liquid, and passing the gas through an alkali.
Xanax will show up on a drug screen. It depends on which type of drug test is being performed to know if it will know how much you take daily. Some drug tests test for the presence of drugs by themselves (the result is either positive or negative only), and some tests will show the amount of the drug in your urine.
No but there are some tests that can detect it
Are you bathing with them, or shoving them up your nose? The things that show up on drug tests are the things tested for in drug tests. Normally that's some combination of marijuana, opioids, cocaine, and methamphetamine, and compounds chemically very similar to those. Some tests are more comprehensive and will show other drugs as well.
Some drug tests are almost instant. Tests for residue on skin for marijuana, cocaine, meth, and several other drugs can be done in real time. Results for drug tests that employers specify can usually be completed in a day. Results for criminal drug tests can take much longer. Toxicology done by the coroner, where so many drug abusers wind up, usually takes 2 or 3 weeks.
No, wellbutrin does not show up on a routine drug test. I was taking for about a month while also taking 3 drug tests per week some of which were 12 panel tests.
The test they had to take was extremely difficult.
