- Chromatography is based on molecules differing physical properties as a means of separating compound mixtures. Group of answer choices True FalseThe flame-ionization detector is used in gas chromatography because the eluates cannot be detected by UV. True FalseChemistry Consider the following chromatogram. The early eluting peaks and later eluting peaks exhibit a problem. Propose a way in gas chromatography to eliminate both problems.
- Gas chromatography cannot analyze mixtures due to the sensitivity of the instrument. True FalseWhy chromatography is an important tool for analysis of organic compounds?1. How does chromatography separate the components of leave samples? 2. Can you use chromatography to purify a mixture? why? 3. What is Rf value and its significance in chromatography?
- Gas chromatography questions:Quality control material in the hematology laboratory is best described as: Question 3 options: A) a stable material used to establish the accuracy of an automated method and normal curve B) a stable material used to monitor the functioning of an analyzer or the performance of a process C) reagents used to perform preventative maintenance D) materials tested to develop a normal reference rangeHow else can chromatography be used? None of these answers are correct. To wash (or remove) unwanted solvents from a mixture. To identify or exclude components in a mixture. To generate IUPAC names for hydrocarbons.
