دستگاه فليم فتومتر مدل XP ساخت كمپاني BWBTech انگلستان
The First Advance in Flame Photometry in the 21st Century.
The BWB-XP flame photometers are high quality, high performance instruments, employing modern technology to ensure that a customer can measure Na, K, Li, Ca and Ba, very simply but with a high performance.
The flame photometers come as a complete package, and only requires the provision of either propane or butane gas to enable it to be used straight out of its package.
The many built in features of this flamephotometer are
- Individual detectors for Na, K, Li, Ca and Ba, plus a Flame (IR) Sensor
- Simultaneous detection and display of all 5 elements
- Digital processing eliminates the need for internal standard methods.
- Two point or multi point calibration
- Choice of calibration units: ppm, mg/l, meq/l, mmol/l
- Unit retains calibration values when in use.
- Automatic start up routine
- Flameout detection and automatic shutdown
- Self diagnostics on set up.
- Diagnostic indicators
- Detection to ensure drain trap filled
- Modular sub component replacement
- In built air compressor
- Electronic air control optimises performance
- RS232 and USB computer interface
- Windows based monitoring software
- SRM (Simple Reporting Module) that allows PC connection for data logging, GLP reporting format, file retention and internet sharing of data. FP - PC.
- Chart recorder output 0-1V full scale
- Gas regulator fitted
- Can be used with propane, butane, LPG
- Universal voltage input
- CE Compliant
- Instruction manual and methods book provided.

What are Flame Photometers?
It is a device used in inorganic chemical analysis to determine the concentration of certain metal ions including Sodium (Na) - Potassium (K) - Lithium (Li) - Calcium (Ca) - Barium (Ba).
In principle, it is a controlled flame test with the intensity of the flame colour quantified by photoelectric circuitry. The sample is introduced to the flame at a constant rate. Filters select which colours the photometer detects and exclude the influence of other ions.
