• This detector is universal in response and nondestructive to
the sample.
• The advantage is that it can be used to respond to
compounds that no other detectors respond well such as
water, CO, or when the we want to recover the separated
compounds for further analysis.
• The disadvantage is the specificity is very little. It detects
almost anything. If we desire the specificity, we need to
remove the interfering compounds from the chromatogram.
