Autosamplers for the flame mode, hydride techniques and
    atomic fluorescence

Autosamplers for the flame mode AS 51s and AS 52s

• make your routine analyses of standards and samples almost fully automatic.

Integrated in the overall concept of the instrument, either sampler can be simply hung directly into the sample compartment:

•  this saves space
•  and minimizes tubing lengths — the best way to prevent contamination in case of real samples.

The intelligent dilution function of the AS 52s makes manual dilution, a time-consuming and error-prone process, unnecessary. Automatically, it dilutes your samples down to a factor of 1:625. If concentrations exceed the calibration range, an automatic clean control prevents contamination of the subsequent samples.

 Autosampler for graghite furnace — more than only a
    sampler

With the MPE 60 z, the autosampler for graphite furnace AAS of liquid samples, automated sample preparation and analysis are easy:

• Automatic generation of reference curves from one or several stock solutions (up to ten points)
• Dosing of extremely small sample volumes with excellent repeatability
• Automatic sample dilution and enrichment by a specified factor
• Intelligent automatic dilution of samples exceeding the alibration range; clean control limits to avoid contamination
• Automatic enrichment of samples below the calibration range
• Unique automatic correction of the immersion depth for every vessel containing sample or other liquid
• Robust, low-noise operation
• Fast, easy adjustment

Its many functions and the automatic running of optimizing routines make the MPE 60 z an intelligent sample preparation.

 Mercury/ Hydride systems

The measurement and monitoring of mercury and such elements as arsenic or selenium down to low ppb concentrations has always been a challenge. In order to keep the amount of these toxic substances under control in the environment, fast methods and convenient, yet flexible systems are required.
If the hydride systems are coupled with the graphite furnace (HydrEA technology), completely new perspectives open up for the measurement of hydride forming elements (such as As, Se, Sb). The option of enrichment in the graphite tube raises detection sensitivity and contamination problems are minimised.
