410 Cold Vapor Mercury (Hg) Analyzer

$0.00

DESCRIPTION

The Model 410 Mercury Analyzer incorporates the Hatch & Ott Cold Vapor Technique for the analysis of trace levels of mercury in drinking, surface and saline waters, as well as domestic and industrial wastes.  Perfect for EPA Method 245.1.

Features

  • Detection limit 10 PPT
  • 400 mm Flowcell for lower detection levels
  • Complete analytical system includes Hg Cold Vapor kit
  • Affordable price perfect for labs with limited budget
  • Quick analysis and recovery time
  • Up to eight point calibration curve
  • Push button Quick-Purge for flow cell flushing
  • RS 232, printer, and analog recorder output
  • Simple to use-minimal operator training
  • D2 Background correction
  • Live technical assistance for the life of the instrument

Summary of method

This method is based on the absorption of radiation by mercury vapor at the 253.7nm line. The mercury is first reduced to the elemental state using the procedure outlined in EPA method 245.1. Air is then bubbled through the sample, speeding the mercury vapor to the absorption cell. The 253.7nm mercury line emitted by the lamp is absorbed by the vapor in the cell in proportion to the mercury concentration. The result is transmitted to the digital readout which can be read directly in concentration of mercury. The instrument has a built-in Peak-Picker which reads peak area. The operator records this reading before purging. The instrument is then ready for the next sample.

Analytical Performance

The Buck 205 is a high energy, microprocessor controlled single beam atomic absorption spectrophotometer. Solid state electronics and simple optics provide the basis for our superior stability and sensitivity. The Ebert mount monochromator and user-selectable bandwidth give the system maximum flexibility. Our short-path dynamic nebulizer/burner configuration is highly efficient. An inert needle, precisely positioned in a high flow venturi, delivers sample to the corrosion proof impact bead. This results in a tremendously high nebulization effect for all types of sample matrices.

220 Graphite Furnace Upgrade

$0.00

Unique Furnace Design :

The Model 220 GF accessory is for PPB level analyses by graphite furnace AA. This fully integrated design uses an innovative, unique technology in a compact powerful furnace module. The quick-mount design permits rapid changeover between furnace and flame heads.

Capabilities:

The unique power supply in our furnace is capable of generating temperatures up to 3000°C in less than a second! This ultra-fast heating rate provides superior sensitivity in refractory elements and carbide-forming metals. The on-board firmware gives the analytical chemist full control of all aspects of the analysis. Gas flows (external, internal, mini-internal and auxiliary are standard), data collection (integrated, real-time, peak height or absorbance area) and electronic parameters for the hollow cathode lamps and the various background correction routines can all be programmed by the operator for maximum results.

Methods:

The Stabilized-Temperature Graphite Furnace AA (STGFAAS) procedure insures the highest accuracy and reproducibility. The 210VGP can initiate multistep sequences with alternate gas purging for fully optimized STGFAAS.

System Integration:

The integration of the controlling software with the furnace module is comprehensive, and methods development time can easily be cut in half by using our protocols to refine an analytical method. The Model 220AS random-access autosampler will fully automate your analytical operations without the need for an external PC to control the system. By incorporating a sample ID table within the software, complete data handling can be done internally.

Specifications:

Dimensions: 16″H x 12″W x 6″D, Net Weight equal to or less than 38 lbs

Back-Mounted Microprocessor-Controlled, high-Frequency (2KHz) Graphite Furnace module with 3000ºC /second heating rate. Maximum Temperature 3000ºC.

Self contained assembly attaches directly to the 210 or 211 AA unit with no external computer interfacing cables or connectors. Contains four ( 4 ) automatically controlled gas ports for sheath, internal, diluent, and auxiliary gas flows.

Preprogrammed furnace temperature programs for all elements.

No external computer required for operation.
