เครื่องวิเคราะห์ธาตุด้วยเปลวไฟ รุ่น: BWB-LI
BWB Flame Photometers มีชื่อเสียงในด้านการวัดค่าลิเธียมที่มีความเสถียรและแม่นยำสูง สูตรที่ได้รับรางวัลนี้ได้รับการพัฒนาขึ้นโดยเฉพาะด้วยการปรับและเพิ่มประสิทธิภาพระบบตรวจจับอาร์เรย์ ที่เป็นกรรมสิทธิ์เฉพาะของBWB
ยี่ห้อ: BWB ประเทศ: สหราชอาณาจักร
BWB Flame Photometers have always been renowned for a highly stable and accurate lithium measurement. This winning formula has been developed further with specific adaptation and optimization of the proprietary BWB optical array detection systems.
A well-earned thank you to Dr. Richard Roman of the University of Mississippi for his invaluable assistance on this Lithium specific FES.
The BWB Li uses multiple lithium detection channels. This latest configuration has been exclusively designed to specifications laid
out though consultation with our customers.
The BWB Li is the first of it’s kind. Engineered with a single purpose,
the BWB Li is the most accurate and advanced lithium flame photometer
(FES) ever manufactured!
Technical Data
Sample rate
3.5 – 7ml/min
Tubing materials
Silicone and Tygon®
Required desk space for Instrument
50cm (H) x 45cm (W) x 45cm (D)*
For Safety reasons the Flame photometer requires 1m of unobstructed space above to allow dissipation of heat from the chimney.

(24in x 22in x 19in)
Weight
Li Flame Photometer – 15.3kg
Shipping – 25kg
Optimal range
Single point calibration
Li 0.05 – 50ppm
Multi Point Calibration
Li 0.05 – 1000ppm
Reproducibility
<1% Coefficient of variability for 20 consecutive samples over ten minutes at concentrations of 100ppm or less. (After instrument stabilisation).
Chemical Interference
Na/K/Li = <0.5% to each other when equal in concentration at <100ppm
Limit of detection (LOD) and
limit of quantification (LOQ)
LOD LOQ
Li – 0.02ppm Li – 0.05ppm
Time to stability
Less than 15 seconds after sample is introduced into the flame
Ions Measured
4 independent Li channels, each providing up to 14 points of calibration
Interfaces
USB
0-2.5 volt output (based on sample concentration linked to element of users choice)
Optional 4-20mA output in place of the above
Optional integrated printer
.CSV and .PDF generated reports and files via FP-PC software
Recommended minimum warm up
time based on ambient temperature
21ºC – 40 minutes
Power requirements
100V – 250V AC at 50 or 60Hz
automatically selecting
Fuel requirement
Propane, Butane or Natural Gas* regulated
to 19Bar. Flow rate of 0.4l/min
*with modifications. BWB Technologies recommends either Propane or Butane for optimum results.
Readout
LCD, four line, alpha numeric, back lit.
