PerkinElmer TurboMatrix 100 Second-Stage Thermal Desorber

Overview

The PerkinElmer TurboMatrix 100 is a benchtop, two-stage thermal desorber engineered for robust, reproducible pre-concentration and introduction of volatile and semi-volatile organic compounds (VOCs and SVOCs) into gas chromatography (GC) or GC–mass spectrometry (GC–MS) systems. It operates on the principle of thermally driven analyte release from sorbent-packed sampling tubes, followed by cryogenic focusing in a low-temperature trap, and subsequent rapid thermal desorption directly into the GC inlet. This dual-stage architecture—comprising primary tube desorption and secondary cold-trap refocusing—significantly enhances sensitivity, peak shape fidelity, and method robustness compared to single-stage desorption systems. Designed and manufactured in the United States, the TurboMatrix 100 meets the mechanical and thermal stability requirements essential for regulated environmental, occupational hygiene, and indoor air quality laboratories.

Key Features

• Two-stage thermal desorption architecture with independent control of desorption oven and cryo-focusing trap temperatures
• Programmable desorption temperature range from ambient to 350 °C, enabling full volatility coverage from C₂ hydrocarbons to high-boiling PAHs and phthalates
• Cryo-trap capable of cooling to −30 °C, ensuring efficient refocusing of early-eluting compounds and minimizing breakthrough
• 20-position automated sample tube carousel for unattended operation, compatible with standard 1/4″ OD stainless steel or quartz sorbent tubes (e.g., Tenax TA, Carbopack B/C, Carboxen)
• Integrated carrier gas flow control and pressure monitoring for precise pneumatic management during desorption, transfer, and trap desorption phases
• Modular design supporting direct coupling to PerkinElmer Clarus® and AxION® GC/GC–MS platforms via heated transfer lines, with optional interfaces available for third-party instruments

Sample Compatibility & Compliance

The TurboMatrix 100 accommodates industry-standard 3.5″ and 6″ sorbent tubes used in EPA Methods TO-17, TO-14A, and ISO 16017-1 for ambient, workplace, and emissions testing. Its thermal calibration traceability aligns with NIST-referenced standards, and its operational repeatability supports compliance with ISO/IEC 17025 quality system requirements. While the instrument itself does not carry FDA 21 CFR Part 11 certification out-of-the-box, its method parameters and run logs—when exported via ASCII or CSV—can be integrated into validated LIMS or ELN environments under GLP/GMP frameworks. All thermal zones feature PID-controlled heating elements and calibrated RTD sensors, ensuring consistent ramp rates and plateau stability per ASTM D6196 and EN 14662 protocols.

Software & Data Management

Control and method development are performed using PerkinElmer’s TurboMatrix™ Software (v3.x or later), a Windows-based application supporting full sequence definition, real-time system status monitoring, and event-triggered logging. Each run generates a timestamped audit trail containing desorption temperature profiles, trap cool-down curves, carrier gas pressures, and valve actuation events—critical for regulatory review and troubleshooting. Raw method files (.tdm) and summary reports (.csv) are exportable without proprietary viewer dependencies. The software supports user-level access control (administrator/operator roles) and allows configuration of automatic data backup to network drives, satisfying basic data integrity expectations in non-validated settings. For laboratories requiring electronic signature and change control, integration with third-party chromatography data systems (CDS) such as OpenLab CDS or Chromeleon is feasible via ASCII output mapping.

Applications

The TurboMatrix 100 is routinely deployed in accredited environmental testing labs for analysis of VOCs in ambient air (e.g., benzene, toluene, ethylbenzene, xylenes), formaldehyde and carbonyls (after DNPH derivatization), and polycyclic aromatic hydrocarbons (PAHs) in indoor air and stack emissions. It is also applied in materials emission testing (e.g., carpets, adhesives, automotive interiors per ISO 12219-4), forensic toxicology (headspace analysis of volatiles in biological matrices), and flavor/aroma profiling in food packaging migration studies. Its recovery performance (>80% across C₆–C₁₆ alkanes and polar oxygenates) has been verified using certified reference standards traceable to NIST SRM 1850a and EU Reference Material ERM-AD410.

FAQ

Is the TurboMatrix 100 compatible with non-PerkinElmer GC systems?
Yes—via custom or vendor-supplied heated transfer line interfaces; users must validate method transfer and ensure carrier gas synchronization.
What maintenance is required for long-term reliability?
Routine replacement of O-rings, septa, and sorbent traps every 200–500 runs; annual calibration of temperature sensors and flow controllers is recommended.
Does the system support internal standard addition during desorption?
No—the TurboMatrix 100 does not include an integrated liquid standard injector; post-tube spiking or pre-tube standard addition is required.
Can it handle humid or particulate-laden samples?
Yes, when paired with appropriate inline moisture traps (e.g., Nafion dryers) and particle filters upstream of the sampling tube.
Is factory service documentation available for this refurbished unit?
Refurbished units include functional test reports and calibration verification records; full service manuals and spare parts lists are accessible via PerkinElmer’s Customer Portal with valid serial number registration.
