HAIS Instrument:

Yes

TABS

Description

Model:

HAIS Instrument

Measurements Provided:

chemical composition of aerosols, both ensemble and for individual particles

General Description:

This is a version of the Aerodyne Aerosol Mass Spectrometer (AMS), with time-of-flight (TOF) capability, built and certified for operation on the NSF/NCAR GV (HIAPER). It is based on the original quadrupole design, but the addition of TOF capability increases the sensitivity and time (hence spatial) resolution and enables characterization of single particles. The basic measurement is size-resolved determination of the chemical composition of sub-micrometer non-refractory particles with spatial resolution typically less than 1 km.
The following diagram illustrates how the TOF capability is incorporated into the AMS:
As flown on the DC8 in DC3, the configuration is as shown in the following figure:
