You want a flexible and
multi-usable GC or GCMS
system with increased
application range and
detection limits!?
Who doesn’t
4th
generation of the world’s most powerful inlet for Gas Chromatography
OPTIC Multimode Inlet changes your
GC or GCMS into a flexible and multi-
usable system with increased
application range and detection limits
One Inlet, More Analytical Options
OPTIC Inlet is much more than any other Inlet
Compatible with most GC’s
Your GCMS would be able to handle:
 Cold and Hot Split/Splitless injections
 Pyrolysis (liquid and solid samples)
 Large Volume Injections
 In-liner derivatisation
 LC-GC coupling possibility
 Headspace
 CryoFocusing on the column
 Thermal Desorbtion
 On-Column injections
 Automatic liner exchange
Direct heating technology
Low thermal mass
Septum or Merlin Seal
Septum purge line
Carrier line
Split line
High power
O-ring
Liner I.D. = 3.4mm
Oven wall
Cooling by Air, CO2, LN2
computer modeled temp. profile Max temp.: 600˚C
Max ramp : 60˚C/sec
Thermocouple
Solvent Monitor
patented
Benefits of OPTIC Inlet
Real Septum Purge flow
Different septa ca be used: Plug type
Disk type
Merlin Microseal ™
Metal column ferrule can be used
Benefits of OPTIC Inlet
Low thermal mass >:
High temperatures (up to 600°C)
Fast ramp rates (up to 60°C/sec)
Fast cool down time
Relatively large liner diameter (3.4 mm i.d.) >:
150µl At-Once LVI
Direct Thermal Desorbtion (DTD)
Difficult Matrix Introduction (DMI)
In-Liner derivatisation
Solid and Liquid sample Pyrolysis
Best temperature profile >:
good transfer of high molecular components
Temperature profiles
No Cold Spot
Good for high molecular components
 No discrimination
 No evaporate from the syringe needle
 More control over the true injected volume
 Less thermal degradation (Less problems with thermally labile
compounds degrade due to the thermal stress upon injection)
 Better reproducibility with SPME
 Very good reproducibility, also using CombiPAL
Benefits of cold injections
Cold injection versus hot injection
Hot injection
Cold injection
Performance Hot versus Cold injection
Autosampler: AOC 20i, GC-MS: QP 2010, Injector: OPTIC 3, Injection volume: 1 µl, Alkane mix: 0.5 µg/ml

Less sample and solvent is needed and
finally more is arrived at the detector.

Split Flow
Column Flow
Transport liner with sample into OPTIC inlet
Seal and purge the inlet. Apply selective exclusion principle for the analysis:
First temperature increased to just below BP of solvent
Solvent is vented through split line
Temperature and pressure ramped up to achieve selective transfer
Dispose microvial after analysis, clean and re-use liner

On-Column solution
 No press fit
 No liner
 No modification to OPTIC
Inlet
 Easy installation
 Real On-Column
 New type Merlin Microseal
can be used
CryoTrap Option
Different ramp rates for same component.
60°C/sec
30°C/sec
10°C/sec
Cryogenic cold trapping is frequently used for narrowing the
chromatographic band and improving the detection limit.
OPTIC-4 Cryotrap is the fastest heating trap > resulting in sharp peaks

Best GC Inlet

  • 1. You want a flexible and multi-usable GC or GCMS system with increased application range and detection limits!?
  • 3. 4th generation of the world’s most powerful inlet for Gas Chromatography OPTIC Multimode Inlet changes your GC or GCMS into a flexible and multi- usable system with increased application range and detection limits
  • 4. One Inlet, More Analytical Options OPTIC Inlet is much more than any other Inlet
  • 6. Your GCMS would be able to handle:  Cold and Hot Split/Splitless injections  Pyrolysis (liquid and solid samples)  Large Volume Injections  In-liner derivatisation  LC-GC coupling possibility  Headspace  CryoFocusing on the column  Thermal Desorbtion  On-Column injections  Automatic liner exchange
  • 7. Direct heating technology Low thermal mass Septum or Merlin Seal Septum purge line Carrier line Split line High power O-ring Liner I.D. = 3.4mm Oven wall Cooling by Air, CO2, LN2 computer modeled temp. profile Max temp.: 600˚C Max ramp : 60˚C/sec Thermocouple Solvent Monitor patented
  • 8. Benefits of OPTIC Inlet Real Septum Purge flow Different septa ca be used: Plug type Disk type Merlin Microseal ™ Metal column ferrule can be used
  • 9. Benefits of OPTIC Inlet Low thermal mass >: High temperatures (up to 600°C) Fast ramp rates (up to 60°C/sec) Fast cool down time Relatively large liner diameter (3.4 mm i.d.) >: 150µl At-Once LVI Direct Thermal Desorbtion (DTD) Difficult Matrix Introduction (DMI) In-Liner derivatisation Solid and Liquid sample Pyrolysis Best temperature profile >: good transfer of high molecular components
  • 10. Temperature profiles No Cold Spot Good for high molecular components
  • 11.  No discrimination  No evaporate from the syringe needle  More control over the true injected volume  Less thermal degradation (Less problems with thermally labile compounds degrade due to the thermal stress upon injection)  Better reproducibility with SPME  Very good reproducibility, also using CombiPAL Benefits of cold injections
  • 12. Cold injection versus hot injection Hot injection Cold injection
  • 13. Performance Hot versus Cold injection Autosampler: AOC 20i, GC-MS: QP 2010, Injector: OPTIC 3, Injection volume: 1 µl, Alkane mix: 0.5 µg/ml Constant 320 Constant 250 Programmed 50 -> 320 Inlet temp.

  • 16. LVI Solvent Vent Monitor Function in OPTIC Sensor Output Time Inject Vent valve closes Sensor in split lineSensor in split line (standard available)(standard available)
  • 17. Difficult Matrix Introduction (DMI)  Raw sample or dirty extract is put into micro vial and placed directly into liner In-injector thermal desorption or pyrolysis of liquid or solid samples What is Difficult Matrix Introduction (DMI)?
  • 18. d) OP TIC Injector e) Ca rrier In Split Flow Column Flow Transport liner with sample into OPTIC inlet Seal and purge the inlet. Apply selective exclusion principle for the analysis: First temperature increased to just below BP of solvent Solvent is vented through split line Temperature and pressure ramped up to achieve selective transfer Dispose microvial after analysis, clean and re-use liner DMI step by step:DMI step by step: What is Difficult Matrix Introduction (DMI)?
  • 19. Pyrolysis Liquid T (°C) t (min) injection solvent elimination pyrolysis 600 40 0 1 5 Liquid injection: simple to automate pyrolysis Sample inlet Vapour outlet - Temperature program to 600°C - Fast ramp rate (60°C/sec)
  • 20. Pyrolysis Solid - Sample in micro vial - Fast ramp rate (60°C/sec) - Temperature program to 600°C - Multi-Shot Pyrolysis possible - Evolved Gas Analysis (EGA) possible
