GC Connections

Taking the improved design approach,

Thermo Electron introduced the Ion Bright

source for its DSQ line of benchtop GC

mass spectrometers. The new source

features improved ion lensing that gains

sensitivity by reducing ion scatter while at

the same time reducing maintenance

cleaning requirements.

The sole entry in a classic non-

spectrometric detector comes from

PerkinElmer/Arnel. The ASD amperometric

sulphur detector delivers equimolar

sulphur response with 10 ppb

sensitivities and six to seven orders of

magnitude of selectivity against carbon.

The detector is available in several

application-specific configurations of the

PerkinElmer Clarus 500 GC system.

Finally, the Intelligent Ion miniature mass

spectrometer from Intelligent Ion Inc.

(Seattle, Washington, USA) uses a non-

scanning double-focusing mass filter and a

charge-coupled diode array in a portable

format. The unit is also able to

accommodate a capillary precolumn.

General Accessories

Only a few general accessories came to my

attention this year. Items fall into this

category if they do not obviously fit

elsewhere.

The Dual Vespel ring inlet seals from

Restek (Bellefonte, Pennsylvania, USA) are

for Agilent split–splitless inlets. The devices

improve sealing and require less torque for

installation than other inlet seals of this

type. Also from Restek, SeCure Y-shaped

connectors are a variation on press-fit fused-

silica column connectors. They constrain the

connector in a metal bracket that hangs

inside the capillary column cage and

prevents undesired tubing disconnection.

Two accessories addressed specific

capillary column performance issues. First,

the Stop-Flow GC kit from Restek is a dual-

capillary column accessory that helps

resolve coeluted analytes while reducing

analysis time by momentarily changing the

column flows to control peak passage

through the columns’ midpoint

connection. Second, the GC Racer

accessory from Horizon Technology

(Atkinson, New Hampshire, USA) is a high-

ramp temperature-programming add-on

for Agilent gas chromatographs that

boosts programme rates at higher

temperatures, well beyond the factory

instrument heater’s capabilities.

Software and Accessories

This year, there were many software

offerings at Pittcon, especially in the

laboratory information management

systems (LIMS) area. In particular, these

booths were organized into a Laboratory

Informatics neighborhood which, as I

walked through, had a little of the flavour of

a carnival midway with competing vendors

located across the aisles from each other. I

could almost imagine them barking out

their sales pitches to all passers-by. Because

of the large number of LIMS products, and

for reasons of conserving space in this

review, I limited this column to mention only

those software vendors that offered new

items directly related to GC instrumentation.

From Thermo Electron, the Device

Development kit for the Atlas

chromatography data system is a

developer’s toolkit that allows rapid

deployment of new LC and GC instrument

technology and a common user interface

to minimize training requirements.

John Wiley & Sons (Hoboken, New

Jersey, USA) has published a collection of

mass spectra of designer drugs that

includes 1400 compounds and 1700 mass

spectra plus 100 chemical warfare agent

compounds. The library is compatible with

search and data-reduction software that

uses the company’s other current mass-

spectral libraries.

Agilent Technologies introduced a new

mass-selective detector deconvolution

reporting software package that performs

target compound analysis with three

independent verification techniques.

Reportedly, it can reduce the time required

for compound identification by as much as

2 h. Agilent also deployed a new version of

their ChemStation software for the 5973

series GC–MS detector that addresses the

requirements for data security, integrity

and traceability of FDA 21 CFR Part 11. The

software enforces secure-user

identification, traceable and auditable

activity records, and electronic sign-off of

records for a closed system.

New GC software offerings from

PerkinElmer include SoftLINK instrument-

control software that operates as many as

four of the company’s Clarus 500 GC

systems from a single TotalChrom 6.2.1

Workstation using either RS-232 or

universal serial bus (USB) ports without

additional intermediary control boxes or

interface cards. The company also

announced its TurboMass V.5.0 reporting

software for its TurboMass GC–MS system,

which adds multiple-ion ratio reporting,

improved report summary, and page-

formatting options based upon the

company’s Communiqué report creator.

Conclusion

Yet again, in 2004 Pittcon proved itself the

flagship annual conference in analytical

chemistry. In the GC arena, instrument,

software and accessory manufacturers

continued to enhance their products with

new technologies and to improve existing

equipment with new ideas. This year, the

largest number of new or improved

products was in the automation category,

followed by instrument systems and

add-ons. Perhaps the showing of so many

relatively expensive offerings signals an

upturn in the instrument business. Next

year’s conference might reveal whether

such a trend is truly under way.
