JTS-150 Photosynthesis Spectrometer

---

  The  JTS-150 spectrometer brings the power of fast kinetics studies using  multiple wavelengths with intensity control into a single experiment.  With the JTS-150 and Smart-Lamp you can use a single experiment setup and collect data using up to nine  wavelengths in real time on a microsecond time scale. Perfect time  correlation from a single sample allows you to view multi-center  reactions in parallel or in sequence. The JTS-150 makes it possible to  monitor every reaction within photosynthesis in a sample with one setup.  In continuous mode data can be collected at a sub-microsecond rate for  viewing faster reactions.

The  JTS-150 measures absorbance or fluorescence using combinations of  detection LEDs and optical emitters. Pulsed LED measurements  (Joliot-type) can be acquired at 10 microseconds between samples (100  kHz). Continuous measurements (not pulsed LEDs) can be acquired at 100  nanoseconds between samples (10 MHz). 

The  JTS-150 has all applications and controls built in and is controlled  from a web browser connected via local Ethernet allowing the instrument  to be controlled from a PC, Mac or even a Linux based system either  directly connected or remotely via the network connection. This software  architecture allows a sequencing interface that simplifies sequence  design and data collection/analysis for researchers without years of  experience and a full opto-electronic suite.

With the newly designed Smart-Lamp,  you can measure any combination of the following photosynthesis  reactions in a single experiment: P700 at 705nm, Plastocyanin at 574nm  and 735nm, Electrochromic shift at 520nm corrected at 546nm, Cytochrome  b6f at 554nm and 563nm with baseline corrections at 546nm and 574nm, and  Fluorescence with or without the flashprobe at 470nm to measure Primary  Fluorescence parameters (Fo, Fm, Fv, Fp, Fv’, Fq’, Fm’, F’, Fm) and  Calculated Fluorescence parameters (qE , qI, qL, qP, NPQ, max PSII  photochemistry, PSII operating efficiency, PSII max efficiency, PSII  efficiency factor or QA), OJIP, Fluorescence induction kinetics. The  smartLED array enables the observation of interactions between any of  the photosynthetic parameters measured by the JTS-10/100 without the  need for complicated experimental setups, in a single run, typically  without any need for averaging. 

Now  you can have powerful insight into the regulation of linear, cyclic and  alternative electron flows and the status of P700, the transmembrane  potential, and fluorescence status and more simultaneously.
