Analytik Jena UK has launched the Novaa 350: a high-performance flame-only atomic absorption spectrophotometer.
Designed for daily laboratory usage, the model features an automatic eight-lamp turret utilising high-intensity hollow cathode lamps with a significantly improved lamp power supply for better performance and speed of analysis.
The Novaa 350 is a fully automated flame system that is available for single- or double-beam operation.
The high-quality optics from Carl Zeiss feature a special covering for protection against aggressive laboratory environments.
The D2 HCL background correction method ensures that accurate analyses can be carried out on samples with difficult matrices.
A built-in self-check system utilises sensors to monitor key safety-relevant parameters, such as gas flow, the burner and the siphon for contamination residue, to ensure the safe operation of the instrument.
The flame is automatically extinguished in the event of a power failure.
A number of optional accessories can be used to further enhance performance.
For large sample throughputs, an autosampler is available with online dilution.
This provides the automatic dilution of samples down to a factor of 1:625 to eliminate errors associated with manual dilution.
If concentrations exceed the calibration range, an automatic clean control prevents contamination of the subsequent samples.
For samples with particularly complex matrices, accessories such as the SFS6 injection unit or the Scraper can be a benefit, according to the company.
The software-controlled SFS6 injection system provides continuous cleaning and flushing of the burner heads to extend the available working time with samples with high matrixes or salt contents.
The Scraper is a software-controlled cleaning device for use with nitrous-oxide flames.
It automatically removes graphite deposits from the burner slot, ensuring continuous and reproducible measuring cycles for routine analysis and avoids the need to shut down the flame for cleaning.
