Can you summarize the principles of chromatography? How would you determine the purity of a chemical sample? What's the difference between dry chemistry and wet chemistry? How do you maintain laboratory instruments? What's the difference between quantitative and qualitative analysis?

Question

Accepted Answer

Chromatography principles, purity determination, dry vs wet chemistry, instrument maintenance, quantitative vs qualitative analysis

Chromatography separates components based on their interactions with a stationary phase and a mobile phase
Purity of a chemical sample can be determined by techniques like chromatography, spectroscopy, or titration
Dry chemistry involves the use of pre-packaged reagents in a self-contained system, while wet chemistry involves the mixing of liquid reagents in a laboratory setting
Laboratory instruments should be regularly calibrated, cleaned, and maintained according to manufacturer's guidelines
Quantitative analysis measures the amount of a substance present, while qualitative analysis identifies the components present without measuring their amounts
