selectivity |
relatively low ; responds to almost all analytes that contain carbon atoms |
relatively high ; responds to analytes with groups of high electro-negativity (nitro-, carbonyl-, and halogen groups)
|
 Terminology |

|
linear response range |
very wide (> 5 orders of magnitude in analyte mass) |
narrow (< 3 orders of magnitude in analyte mass) |
|
