TID-1-NITROGEN: selective for some Nitro and Halogenated
compounds at femtogram and picogram levels, most
Oxygenates at picogram and nanogram levels with especially large responses for
Phenols, Carboxylic Acids, and Glycols.
TID-1-AIR(OXYGEN): selective for Halogenates and Nitro compounds at
picogram levels, some Oxygenates at picrogram and
nanogram levels, water vapor at ppm levels, and
microgram levels of Methylene groups in Linear
Chain Hydrocarbons, FAMES, and Triglycerides (CCID mode).
TID-3-NITROGEN: selective for
volatile Halogenates such as Trihalomethanes with minimal peak tailing.
TID-2-HYDROGEN/AIR (NPD): selective for N or P compounds at
sub-picogram levels with minimal tailing of
P peaks.
TID-4-HYDROGEN/AIR (NPD): our
best N-response (femtogram detectivity).
PTID: selective for P compounds with very large
signals and suppressed N-response.
FTID (Flame Thermionic Ionization): selective for
Nitrogen or Halogen compounds at nanogram levels and
above.
REMOTE FID: selective for Pb, Sn,
P, or Si compounds with picogram detection.
FID: universal response to all organics.
TANDEM
TID/NPD(TID) and TID/FID: simultaneous signals from
two detectors with many possible combinations.
Examples
of
some applications:
 |
drugs of abuse with NPD (TID-4). |
|
|
pesticides and environmental pollutants with NPD (TID-2 or TID-4). |
|
|
nitro explosives with TID-1 and NPD (TID-4). |
|
|
phenols and carboxylic acids in foods and
flavors analyses with TID-1. |
|
|
oxygenates and N-compounds in petroleum samples with TID-1 and NPD. |
|
|
trihalomethanes with TID-3. |
|
|
Pb or Sn in complex matrices with REMOTE FID and organic-fueled flame. |
