Agilent 7200 Accurate-Mass Q-TOF GC/MS (G3851A)

The 7200 Q-TOF incorporates a hexapole collision cell blanketed with nitrogen gas, to improve the ion fragmentation prior to detection quantification. It also includes new ion optics for focusing the ions prior to the flight tube and detector. This configuration has advantages for many applications. The data is interpreted through the use of the MassHunter WorkStation software, which provides quantitative and qualitative analyses of the data obtained.
The 7200 Q-TOF can operate in either TOF mode or MS/MS mode. When operating in TOF mode, the instrument can obtain high resolution, accurate mass measurements, and fast full spectrum acquisition. MS/MS mode provides high resolution, accurate mass measurements, and fast full product ion spectra with high sensitivity. These features make the 7200 Q-TOF a good tool for solving complex analytical problems, resolving structural elucidation of unknowns, and confirmation of nontarget compounds.


  • Three turbomolecular vacuum pumps
  • Rotary vane foreline pump
  • Independently MS-heated removable EI or CI ion source
  • Removable ion source (RIS), which allows quick change from
    EI to CI source with minimal loss of vacuum in the
  • Independently MS-heated hyperbolic quadrupole mass filter,
    which can be heated to high temperatures, minimizing the
    contamination typical with low temperature analyses
  • Single hexapole collision cell
  • Vacuum-insulated flight tube with dual-stage ion mirror
  • Fast electronics, allowing fast sampling rates
  • Analog-to-digital detector
  • Independently GC-heated GC/MS interface with automatic
    retraction during source removal

Agilent 7890B Gas Chromatograph System

The 7890B Gas Chromatograph (GC) System is the world’s most widely used GC system, featuring accurate temperature controls, precise injection systems, and high performance Electronic Pneumatic Control (EPC) modules for good retention time and area count repeatability.


  • Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab
  • Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column
  • Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline with a minimal amount of signal drift
  • Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection
  • Integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides low ppb detection, equi-molar response, and quantitation for sulfur or nitrogen contaminants without quenching from matrix
  • Carrier Gas Options: Helium Conservation Module, Hydrogen Sensors and Alternate Carrier Gas Solutions dramatically reduce the amount of helium used to offer flexibility in your laboratory
  • Large Valve Oven (LVO) allows for the combination of multiple methods and simplified maintenance
  • Multimode inlet (MMI) serves as a programmable temperature vaporizing injector with flexible capabilities
  • Agilent Inert Flow Path provides increased sensitivity for active compounds, from injection to detection
  • Low Thermal Mass (LTM) modules, up to 4 installed and operating, increase sample throughput with rapid column heating and cooling

Agilent 7693A Autosampler

The Agilent 7693A ALS (Automatic Liquid Sampler) provides reliable, fast, and precise injections for Agilent GC and GC/MS systems. The modular design allows this autosampler to grow with your lab.


  • 150 sample vial tray allows longer unattended operation
  • Dual simultaneous injection saves time by doubling sample throughput
  • Fast injection technology minimizes needle discrimination and enables use of external standards
  • Sandwich injections of three layers eliminate manual error from internal standard, surrogate, or protectant additions
  • Sample heater and mixer dramatically improves high molecular weight chromatographic results
  • Heat the entire tray or cool it to sub-ambient temperatures to meet your lab’s needs
  • Modular design allows the flexibility to easily move the sampler from GC to GC or start with a single injector and upgrade as needed
  • Priority sample capability. There is no need to stop the sequence to add next most important sample
  • Barcode reader allows the system to perform specific actions on mismatch, ensuring chain of custody Agilent Barcode Printing Solution.
  • Extend the useful life of the 6890N GC by upgrading aging autoinjectors to 7693A

Our refurbished instruments are tested and repaired to meet factory specifications. We follow Installation Qualification, Operational Qualification, and Performance Qualification protocols (IQ, PQ and OQ).

Our team of skilled technicians are experts at fixing analytical instruments. We have been working with Agilent, Waters, Perkin Elmer, Sciex, Shimadzu, and Thermo instruments for many years. We are constantly updating our knowledge with the latest technology and information to enable us to deliver the best support in the industry. We provide value added support and qualification/validation with all our instruments. We endeavor to develop strategic partnerships with our clients so that they consider our team as an extension of their employees. We are an affordable alternative to many normally expensive business projects.

Warranty and Support
We offer warranty on all refurbished instruments. Warranty starts at 3 months, with the option to extend the period. While your instrument is on warranty, we will provide Email ( and phone support and troubleshooting if you require assistance. If there is ever anything wrong with the equipment, we will replace it. Warranty begins from the date your equipment is successfully delivered. Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty.

We will match our warranty duration with our competitors.

Installation and Training
If you purchase equipment from Spectralab Scientific, we offer installation and familiarization by our service technicians for an additional fee. If the instrument is particularly complicated, we highly recommend this service. If you’ve purchased less-complex equipment from us that you would like to install yourself, we can provide Team Viewer, email, or telephone support for no additional cost.

Large Inventory
We have a large inventory of equipment, components and parts in stock. You can find all the equipment you need for you lab in our store, as well as mix and match components for your systems.

International Shipping
We have sufficient export experience, including professional packing and proper documentation. Complementary shipping and handling can be applied upon immediate purchase. We include customs fees, brokerage, and duties for shipping to the US.

Price Matching & Discounts
Purchasing our refurbished instruments can save you anywhere from 30% to 90% compared to purchasing brand new. We will try to match or beat any price from our competitors, so feel free to inquire! Complementary shipping and handling can be applied upon immediate purchase.
