INNOTEG TB2101 Manual Thermal Desorption Tube Spiking Station

Overview

The INNOTEG TB2101 Manual Thermal Desorption Tube Spiking Station is an engineered benchtop solution for the precise, reproducible preparation of calibration standards in sorbent tube-based volatile organic compound (VOC) analysis. It operates on a controlled liquid spiking principle: analyte solutions are delivered via calibrated syringes into thermally stable sorbent-packed tubes under a regulated inert purge gas flow—enabling solvent evaporation and uniform analyte deposition onto the sorbent bed without channeling or breakthrough. Unlike automated spiking systems, the TB2101 provides full operator control over injection volume, needle insertion depth, dwell time, and purge duration—making it particularly suitable for method development, reference material verification, and low-throughput compliance labs where flexibility and traceability outweigh high-speed throughput requirements. Its mechanical architecture eliminates manual needle stabilization during purging, reducing inter-operator variability and protecting fragile stainless-steel or polymeric frits from mechanical damage.

Key Features

• Vertical fixed-position syringe mount with depth-limited needle guide ensures consistent penetration across all tube batches—preventing frit deformation and ensuring repeatable analyte distribution.
• Dedicated thermal desorption tube holder accommodates standard 3.5-inch × 1/4-inch (89 mm × 6.35 mm) sorbent tubes, including multi-bed configurations (e.g., Tenax TA/Carbograph 1TD/Carboxen 1000).
• Integrated liquid standard tray with labeled positions for up to 12 vials (1–4 mL capacity), plus separate solvent reservoir slot for methanol, CS₂, or other elution solvents.
• Adjustable mass-flow-controlled purge gas system (N₂ or He) with fine-tuning capability (±5 mL/min resolution), supporting optimized drying kinetics for diverse analytes—from light C₂–C₅ hydrocarbons to semi-volatile phthalates and SVOCs.
• Compact footprint (280 × 220 × 180 mm) and lightweight construction (<4.2 kg) enable deployment in fume hoods, mobile labs, or shared instrumentation spaces without permanent installation.
• Mechanically indexed alignment between needle tip and tube inlet minimizes lateral stress during insertion—critical for maintaining integrity of packed-bed geometry and minimizing void formation.

Sample Compatibility & Compliance

The TB2101 supports spiking of single- and multi-bed sorbent tubes used in EPA Methods TO-17, ASTM D6196, ISO 16017-1, and EN 16705 for ambient, indoor, and occupational air monitoring. It is compatible with common sorbents including Tenax TA, Carbopack B/C, Carboxen 1000/1016, and graphitized carbon blacks. While the instrument itself does not generate electronic audit trails, its mechanical repeatability supports adherence to GLP documentation practices when paired with standardized SOPs, handwritten spiking logs, and secondary verification (e.g., post-spiking gravimetric checks or split-loop GC-MS validation). No electrical certification (e.g., CE, UL) is required due to absence of powered components.

Software & Data Management

The TB2101 is a fully manual, non-electronic instrument with no embedded firmware, display, or data output interface. All operational parameters—including syringe volume, tube ID, solvent lot number, spiking date/time, purge flow rate, and operator initials—are recorded externally using laboratory notebooks or LIMS-integrated spreadsheets. This design eliminates software validation burden under FDA 21 CFR Part 11 while preserving full procedural transparency. Users may integrate spiking records with chromatographic data systems (e.g., Thermo Chromeleon, Agilent OpenLab) via manual metadata linking during sequence setup.

Applications

• Preparation of certified reference standards for EPA TO-17 compliance testing in ambient air quality monitoring networks.
• Generation of multi-level calibration curves for indoor air VOC profiling (e.g., formaldehyde, benzene, limonene, naphthalene) per ISO 16000-6.
• Forensic toxicology workflows requiring trace-level spiking of target compounds (e.g., accelerants, illicit drug metabolites) into thermal desorption tubes for GC-MS confirmation.
• Product safety assessment in consumer goods—spiking of fragrance compounds, plasticizers, or off-gassing volatiles into tubes for emission chamber validation (e.g., ASTM D5116, ISO 12219-4).
• Method validation studies evaluating sorbent breakthrough volume, recovery efficiency, and storage stability per USP .

FAQ

Does the TB2101 support automated volume delivery or programmable sequences?
No. The TB2101 is strictly manual: syringe actuation, timing, and gas flow adjustment require direct user intervention.
Can it be used with 6.5-inch or micro-sized thermal desorption tubes?
No. It is mechanically constrained to 3.5-inch × 1/4-inch standard-format tubes only.
Is purge gas flow calibrated or certified?
The integrated flow regulator is factory-set and user-adjustable; however, periodic verification with a NIST-traceable flowmeter is recommended for ISO/IEC 17025-accredited labs.
What maintenance is required?
Routine cleaning of the needle guide bore and tube holder recess with IPA; annual inspection of syringe mount rigidity and purge line integrity.
Are replacement parts such as needle guides or tube clamps available separately?
Yes—INNOTEG supplies OEM-compatible spare kits (P/N TB2101-SK1) including precision-machined aluminum guides and silicone O-ring sets.
