The “Compromise”

high SPEED vs resolution

new 2012+ extended to 4 metres MAX per module but 8 metres 2 modules in series

column resistive heating 6 foot long MAX ) . . . compromised “intrinsic” column efficiency
0.28mm ID Columns ~3000 plates/meter Total N(t) 6000
compared to high resolution 0.28mm ID  30m N)t) 90,000
BUT analyses in 2 minutes vs 20-30 minutes optimised

“old” GCs : large Lab GC Ovens

High Enengy;kilowatts;  slow heating 60degC/min. . .  at lower temp ranges
0-100C; 40 100-200; 200-300 30 300-400 ???
Cool Down 5minutes to 50C, 10mins to 40C

“new” Calidus FAST GC

300 Watts max; 300degC permin . . . ideal for portable applications
ambient +5 degC to 400 degC
Cool down < 2mins to 40 degC

Fast GC vs idealised but slower R&D type separations

HC to C20 Details Restek E1387 Mix

Higher resolution > L and much greater time required

If you don’t need the Resolution then you can save time
- Accuracy improved . . . 10-20scans per peak

accuracy depends on speed of the A/D / time slicing of the Data Sys across peaks - obvious compromise in idealised Restek chromatogram
 - also may suffers in accuracy perhaps
re 1 to 3 scans per peak ? ideally minimum of 10scans per peak

see accuracy proven below for typical FAST GC
. . . obvious a simulated chromatogram or perhaps on a high speed
TOC GC/MS sytsem and “idealised”

ComparisonFastVsHR
Calidus-Speed

Speed Relevance
from Process Control GC Perspective

Cost savings re finesse of production control raw materials product throughput etc - invaluable

Zoom

Who would Use Calidus FastGC Enviro Labs
Idealfor  field or lab preliminary scanning tool
 . . . for follow-up detailed High(er) resolution of target samples by GC and/or GC/MS
4metres (max of Calidus) 0.1mmID MXT Nt 32,000
 = 15metres 0.25mm
Peak Resolution
re Packed GC Column 30ft of 1/8”OD ~Nt 16,000

Huge potential; savings for work intensive laboratories

Process Control GC
many application can run at 20 times the speed
Economies of scale with finer control of process plants

2D-GC Applications
Heart Cutting eg First seperaton om a non-polar column with overlapping peaks separated on a polar column all in-line . . . on-line.
- can be equivalent to a single column separation with “millions of plates

Fast GC AND TSE
increases LOD by refocusing “broad” peaks/ post column . . . x14 to x40; particularly for many volatiles on a (mini-) TCD detector
requires air compressoer and “vortex” cooling

DISADVANTAGES Injected on-column Sample Capacity
 is less and requires a Split sample
BUT Sharper Peaks means LOD Limit of detection
so ~ the same

Calidus-Reroducibility

Zoom

Fast_C5-C44

FAST GC
high speed . . . separation in <120seconds
NOT minutes
AND
High Temperature C60+ or higher

far better than any process Control GC anywhere
“proven” to ASTM D2887 standards

D2887_FastvsGC

Process Control - SIMDIST D2887

“Approved” to ASTM Standards
Calidus certification . . .  pending

18x times Faster

Calidus 2D GC + TSE

a simple powerful 2D-GC gas separation
- heartcut to 2nd column - 4mins ASK for details

with TSE capability

Zoom

TSE ( Targetted Signal Enhancement )
Vortex Cooling
- requires 80psi 4cfm air compressor but up to x75 increase in sensitivity for TCD
for Process GC : 6.5x3.x2” preferably separate or GC oven
- sub ppM LOD for CO2, CO, C2+ HCs, water, S-Compounds (?) potentially N2O (???) application to Lab GC ???? maybe ?
