JB-750 Optical Emission Spectrometer
The JB-750 is JIEBO's flagship PMT-based optical emission spectrometer for high-precision metal-grade certification and quality assessment. Its 750 mm Paschen-Runge optics, vacuum chamber and single-spark pulse-integral algorithm give it the spectral resolution and signal-to-noise of legacy German PMT systems at a fraction of the cost.

Frequently asked questions
Why choose a PMT system over CMOS in 2026?
PMT detectors still outperform CMOS for high-end trace-element work and long-term stability. The JB-750 uses PMTs because the application — certification labs and aerospace QA — demands signal-to-noise and lifetime that CMOS cannot match yet.
How does JB-750 compare to the Noble T7?
The T7 is CMOS-based and covers 120–800 nm with 401 mm optics; suitable for high-throughput research. The JB-750 uses PMT and 750 mm optics — higher spectral resolution, better trace-element sensitivity, but larger and more expensive. Choose JB-750 if your work is certification and your samples justify the precision.
What is the argon and power consumption?
Argon 99.999 % (5N) with intelligent argon management to reduce consumption between sparks. AC 220 V / 50 Hz single-phase. Anti-reflux vacuum pump prevents optical chamber contamination.
What lead time should I plan for?
Approximately 30–45 working days for built-to-order PMT configurations. Stock units (common matrix configurations) ship in 15 days.
