DMA-1

Compact Direct Mercury Analyzer

The DMA-1 mercury determination system does not require any sample preparation or other wet chemistry before the analysis. This means ease of use, low running cost and no more necessity to purchase, handle and dispose hazardous chemicals.

Best analytical performance

ACCURATE RESULTS

The DMA-1 achieves a detection limit as low as 0,003 nanograms of mercury and is capable of measuring up to 1.500 nanograms of mercury, equivalent to a concentration of 15 mg/kg (15 ppm) on a 100 mg sample analysis.

SAMPLE MATRIX

The DMA-1 produces matrixindependent results. The instrument is calibrated using aqueous standards and then analyzes organic and inorganic solid samples. Just one method is used to analyze a variety of different matrices making the DMA-1 extremely easy to use.

PRECISION AND STABILITY

The DMA-1 provides reproducible results over a broad range of samples, such as polymers, food and feed, and oils, for instance. The instrument calibration lasts for months of operation, and the results are stable over time.

MEMORY EFFECT

The DMA-1 does not virtually suffer from any memory effect. The instrument software features the ‘Autoblank’ function, by which the user preset a satisfactory blank level. If that level is exceed the instrument automatically runs blank cycles until the expected level is reached. This is important when analyzing a series of unknown samples.

SAMPLE AMOUNT

Up to 1,5 grams of solid or 1,5 mL of liquids can be analyzed. This is particularly important for the analysis of heterogeneous materials or for samples with a very low mercury concentration.

Delivering performance with

Easy-to-Use Technology

The DMA-1 is operated via a compact control terminal with easy-to- read, bright, full-color, touch screen display or, alternatively, by a Windows-based computer. The terminal is provided with multiple USB and RS-232 ports for direct printouts of methods and runs, and for interfacing the instrument to an external balance. The terminal runs Milestone’s unique EasyCONTROL software, providing simple and intuitive, but extremely flexible and powerful control over the analytical process. All sample parameters, including furnace temperatures, method profiles, absorbance signals, results, and calibrations are saved.
