The Tekran 2700 Methyl Mercury Analysis System offers an automated solution for complex and time consuming manual techniques. The 2700 is a fully-integrated, gas chromatography, cold-vapor atomic fluorescence spectrophotometer (GC-CVAFS). The 2700 can analyze distilled waters, extracted or distilled tissues and solids, and allows direct analysis of suitable water samples. The Tekran 2700 (MDL=0.002 ng/L) is operated via state-of-the-art, intuitive software. The 2700 offers the capability to interface with other instrumentation such as an ICP-MS for isotopic analysis, and has the ability to characterize multiple mercury species.

The Tekran 2700 Methyl Mercury Auto-Analysis System gives analytical laboratories and researchers automated alternatives to time-consuming and complex manual EPA method 1630 techniques. The Model 2700 offers a fully integrated, compact unit based on atomic fluorescence detection and operated via reliable, intuitive software. The system is pre-programmed to run EPA Method 1630, However, the Model 2700 offers complete method customization including: 1) GC column temperature ramping, 2) Programmable analysis cycle settings, 3) High temperature purge cycles and 4) Choice of trap and GC column. The 2700 will also seamlessly interface with ICP-MS or other analytical instruments.

The Model 2700 enclosure is specially designed for easy access to all serviceable components (e.g. GC column, detector, Tenax/Carbo trap). The Model 2700 includes integrated trouble shooting features such as pre-programmed leak check event cycles and software-based step by step detector maintenance guides. The superior design and features make the Model 2700’s the analyzer of choice for your methyl mercury laboratory.

  • Remote Operation & System Monitoring
  • Free Lifetime Technical & Analytical Support

Superior Atomic Fluorescence Detector
The 2700’s florescence detector features all new electronics, flow cell and optical filter to improve the already extraordinary sensitivity, stability and selectivity. The UV lamp is temperature controlled. An optical feedback arrangement ensures constant lamp intensity over the course of the run and from day to day. The AF detector has an argon optical path purge and highly sensitive photomultiplier. No other mercury detector incorporates all these features.

Designed for Flexibility
The 2700 comes ready to operate with a standard EPA Method 1630 compliant analytical setup. However the flexibility of the 2700 is unsurpassed allowing customization for specific applications. The fully-integrated gas chromatography (GC) oven is programmable and accepts both capillary and packed GC columns. Oven temperature ramping and a capillary GC column yield extremely well defined peaks. Fully programmable analysis cycle parameters provide researchers an unparalleled ability to create modified and experimental analytical methods. It will also interface seamlessly with other analytical instruments.

Expert Support
The Series 2700 comes with a Quick Start Guide that will have you up and running in minutes. The system enclosure has been specially designed to allow easy access to all serviceable components. Ask about our on-site setup and training capabilities. We offer remote system evaluation, optimization and testing along with unlimited telephone/email support in the event you require assistance. Your 2700 will be supported by a full team of Tekran application scientists, researchers and engineers with a combined 80+ years of expertise in mercury analytical systems.
