5 CALIDUS Models combine various standard modules to provide general or specific applications and expanded measurement
capabilities. Each of these models can be installed as a plug and play module within the Calidus process analyzer enclosure.
CALIDUS Model 101 - 3 modules, a Sample Processing Unit, a Programmed Temperature Column Module and a
Detector Module interfaced with the ChromPerfect chromatography data system and fully integrated with LineUp
running on a Windows PC. The user may select either a micro FID or TCD and one of the available different PTCMs
to separate and measure fixed gases and hydrocarbons up to C44.
CALIDUS Model 101 HT - a 101 with a PTCM using High Temperature MXT-1HT Sim Dist column and a micro FID
module specifically for determination of boiling range distribution of petroleum products and biodiesel
formulations up to C50 in boiling point. The analyzer is interfaced with the ChromPerfect chromatography data
system, SimDis 2000 software, and fully integrated with LineUp running on a Windows PC. An ASTM method for
Ultra Fast Micro GC 2887 is currently under development based on the CALIDUS Model 101 HT.
CALIDUS Model 201 - 4 modules, 2 PTCMs in series with one Sample Processing Unit and one Detector Module
interfaced with ChromPerfect chromatography data system and fully integrated with LineUp running on a Windows
PC. There are two major advantages for having two PTCMs in series. First is the ability to leverage selectivity of
different stationary phases. And second, is virtually doubling the column length for even greater separation power
up to C44.
CALIDUS Model 301- 5 modules, a Sample Processing Unit with a single injector connected to a splitter dividing the
sample between two PTCMs in parallel, each with a single micro FID or TCD Detector Module. The Model 301
handles hydrocarbon samples with a wide range of boiling points and a wide range of concentrations (% to ppm)
with better separation and faster analysis all without complicated valve schemes and resultant additional hardware.
CALIDUS Model CS (Column Switching) - 5 modules, a Sample Processing Unit with a single injector connected to a
6-port diaphragm/plunger column valve, two PTCMs in parallel, and two detector Modules. This model can be
plumbed to perform heartcutting from one PTCM with its own FID or TCD Detector Module to a second PTCM with
its own FID or TCD Detector Module. Backflushing configurations are available too. This model is used for analysis
where a specified discrete hydrocarbon (s) must be separated and measured from a defined stream or sample
composition typically within a required time frame with optimum selectivity (up to C 12).
