| Mercury Analyzer with Pre-concentrator |
| The Tekran Series 2600 system allows the analysis of ultra-trace levels of total mercury in liquid samples. It offers unparalleled sensitivity and flexibility for those who require truly sensitive total mercury analysis. |
The system can implement a wide range of different analytical techniques, depending on the requirements of your particular application. Unlike conventional systems, the Series 2600 is available in a wide range of configurations, with options to suit your budget. The system can perform virtually any type of ultra-trace total mercury analysis. Series 2600 modules can be interconnected by the end user, allowing easy migration from a starter system to a fully automated, high throughput configuration. Each module is described in greater detail on its own page, below.
The instrument is capable of providing a fully automated implementation of the new US EPA Method 1631. This method is capable of measuring waters with a detection limit of much less than the required < 0.5 ng/L (ppt) |

| Mercury Monitoring |
| The Tekran Model 1135 Particulate Mercury Unit is used together with the Model 1130 Speciation Unit and the Model 2537A Mercury Analyzer to simultaneously monitor particulate bound mercury (HgP), elemental mercury (Hg0) and reactive gaseous mercury (RGM) in ambient air. The system allows fully automated, unattended operation with all three components being concurrently measured. |
Although the majority of atmospheric mercury is present in elemental form, differentiation among the three types is important due to the widely varying local impacts of each type. (Particulate and reactive gaseous mercury have higher wet and dry deposition rates than does elemental.) Ambient air speciation is of particular interest close to industrial sources such as waste incinerators which often discharge the majority of their mercury emissions in particulate or ionic form.
One of the greatest problems with conventional particulate mercury measurement methods is that reactive gaseous mercury will be trapped on the filter medium along with the particulate bound mercury. This can result in large measurement artifacts. The Tekran speciation system solves this problem by removing the reactive
gaseous component using a denuder before
sampling the particulate mercury
