Using GC MS (Gas Chromatography Mass Spectrometry) you may detect multiple substances within a sample and in very trace amounts. Titration will tell you the concentration of a solution, and is more subject to error.
You can measure the quantity of the stuff you're looking for much more exactly with GC-MS. Also, you can detect several sorts of molecules at once, whereas you need a pure probe for titration.

Why iodometic titration is better than iodimetric titration?
Iodometric titration is better than iodimetric titration for the determination of reducing agents, as it directly measures the amount of oxidizing agent present. This method is more precise, as it involves the direct reduction of a known quantity of iodine to iodide ion. It is also less prone to interference from side reactions compared to the indirect measurement in iodimetric titration.
Why is GC MS better than titration?
Using GC MS (Gas Chromatography Mass Spectrometry) you may detect multiple substances within a sample and in very trace amounts. Titration will tell you the concentration of a solution, and is more subject to error.
Why is Volume of HCl used for blank titration is more than volume of HCl used for oil titration?
The blank titration is used to determine the exact amount of acid needed to neutralize any impurities in the titration setup, such as the indicator and solvent. This additional volume of acid is accounted for in the blank titration and is subtracted from the volume of acid used in the titration with the oil sample.
How many tipes of titration?
There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.
Why kmno4 is added slowly in the titration?
KMnO4 is added slowly in titration to accurately determine the endpoint of the reaction. Rapid addition can lead to overshooting the endpoint, resulting in an inaccurate titration. Slow addition allows for better control and more precise determination of when the reaction is complete.

Can a blank titration reading be greater than sample titration?
yes.

Why do you use internal standards in GCMS?
For quantification of unknown analyte
Is LC MS more reliable test for Newborn screening or is it GC MS?
LCMS (actually) LCMS/MS goes the half way for newborn screening. Its then the GCMS which comes for rescue. It clarifies the results given by LCMS and says with accuracy whether it is a positive or a negative case, against what was indicated in the LCMS screening. GCMS is mostly based on urine sample while LCMS needs blood spots. Thats where GCMS already scores a big point above LCMS. Further, GCMS "confirms" a disorder, while LCMS stops at "maybe". GCMS tests for a massive range of disorders while LCMS is limited to a few class of disorders. GCMS is the future of screening, while LCMS is the present of screening.

How do you pass a 10-50 GCMS drug test?
Don't do drugs.

What is over-titration?
Over-titration refers to the process of adding too much titrant during a titration, resulting in an endpoint that goes beyond the equivalence point. This can lead to inaccurate results as the excess titrant can skew the calculations.
Why AC is used at high frequncy in conductometric titration?
AC is used at high frequencies in conductometric titration to minimize electrolysis effects and polarization at the electrode surface. At high frequencies, these effects are reduced, resulting in better sensitivity and accuracy of the titration measurements. Additionally, using high frequency AC helps to maintain a constant electrolyte concentration and minimize errors in the conductometric titration process.
