Z780 LED Panels are primarily intended for installation in growth rooms and chambers, or for other similar applications where controlled, large-area illumination is of high importance. The Z780 LED Panels provide high-intensity light with uniform light distribution. They are manufactured as single color (cold white as standard) or bi-color series; each color being separately controlled in intensity by the power supply. Infrared LEDs (735 nm) are added in both the single color and bi-color panel version so as to ensure optimal conditions for plant growth. Infrared LEDs can also be controlled separately.

Z780 LED Panel dimension is 27 x 81 cm; it consists of two joined units 27 x 40.5 cm. The panel is delivered with a mechanical rack and a power supply, which is positioned on the top side of the  panel.

The panels are manufactured in three versions differing in power input and maximum reachable intensity (measured in 1 meter distance from the light source):
Version A: maximum reachable intensity 500 µmol(photon).m^-2.s^-1 (cool white)
Version B: maximum reachable intensity 1,000 µmol(photon).m^-2.s^-1 (cool white)
Version C: maximum reachable intensity 1,500 µmol(photon).m^-2.s^-1 (cool white)

As an option, the LED Panels can be supplied with the Light Controller or Light Studio Software; both enable precise control of the light mode, timing and intensity via user-defined protocols.  Contact Qubit System for more information.

Key component of the Gas Control System is the A360 Gas Control Module.

The Gas Control Module (A360) controls a subsampling pump which samples the gas from the chamber and carries it via a flow monitor at a preset flow rate to a gas analyzer (for example Q-S151 CO2 analyzer) .  The analog signal from the gas analyzer and the Flow Monitor (Q-G266) are collected by the Gas Control Module and if the target gas concentration is below the preset levels the Gas Control Module turns on the MFCs for injection of the target gases into the chamber.  The gas injected into the chamber is mixed by fans and  measured periodically when the subsampling pump is activated. The output of the gas analyzer and the flow monitor are logged by a data acquisition interface and software.

The Gas Control Module (A360)  calculates the gas injection period from the differntial between the upper threshold and the actual gas concentration measured by the gas analyzer.  The design of the system avoids the possibility of overshooting the target gas concentration as may occur in systems that employ sollenoid controllers rather than mass flow controllers to inject gases.

Components of the Gas Control System:

• Gas Control Module (A360)
• Gas Analyzer (for example Q-S151)
• Gas Pump (Q-P651)
• Flow Monitor (Q-G266)
• Mass Flow Controler 1 (for example 13CO2)
• Mass Flow Controller 2 (for example 12CO2) (optional)
• Data Acquisition Interface
• Data Acquisition Software

Sample of Data Collected:

Qubit Systems can customize your Gas Control System to your specifications.  Please contact us for details.

The Dissolved CO2 (DCO2) Systems are designed to measure the dissolved pCO2 in water at atmospheric pressure.  The systems are composed of a DCO2 sampler with accessories, a non-dispersive infra red CO2 analyzer with a built in gas pump, data interface and software.  The DCO2 sampler is the key component of the system as it samples pCO2 from the liquid and carries it to the IRGA.  The DCO2 sampler is  covered with a PTFE (polytetrafluoroethylene) membrane which allows it to be submerged in water (up to 2 ft).  The CO2 gas dissolved in water diffuses across the PTFE membrane into the sampler and is carried to the CO2 analyzer in a closed loop fixed volume gas stream for detection.  Liquid flow past the sampler is necessary and stirring is highly recomended to speed up the response time.

Applications:

• Algal Cultivation (Bioreactors)
• Ocean Acidification Studies
• Fermentation Studies
• Aquaculture
• Environmental Monitoring
• Waste Water Management
• Food and Drink Industry

Features:

• Measure dissolved CO2 in fresh and seawater
• Customized to desired pCO2 range (ppm to 100%)
• Based on diffusion of CO2 out of the liquid
• Based on Infrared gas analysis
• Insensitive to carbonates
• not based on pH measurements

The PTFE membrane is permeable to gases but not to water at atmospheric pressure.  The system detects dissolved partial pressure of CO2 in water and is insensitive to carbonates.  Note that this determination of CO2 partial pressure is not based on pH measurements.  Water flow past the sampler is necessary to ensure the equilibrium with the surrounding liquid.  The partial pressure of CO2 is converted to concentration of CO2 in water at a given temperature and a partial pressure of 1atm.   If temperature probe is purchased with the system (optional) and temperature data is logged temperature correction may be applied automatically (optional).  The DCO2 Systems can be configured for various ranges of CO2 concentrations from ppm to 100% in gas phase. 

Note that the response time of the system is slow (4-10 min) due to diffusion across the PTFE membrane.  The response time depends on the flow of the liquid past the DCO2 sampler, hence good stirring of the solution is essential. 

The analog signal from the IR CO2 Analyzer is digitized by the C410 LabPro interface  under control of C901 LoggerPro software in the computer.  

sample data:

Included with the DCO2 System:

• CO2 Analyzer with built in pump (S157-P for 0-2000ppm range or S158-P for 0-10% range) (custom ranges also available)

A collaborative design effort between Qubit Systems and Morgan Scientific has led to the Q-CPX Breath by Breath Cardio-Pulmonary System. The focal point of the development was to provide an advanced system suitable for teaching and research in university kinesiology and physiology labs.

The key feature of the system is fast gas analysis using infra-red and laser diode technology. Precise flow and volume acquisition are assured across the wide range of physiological measurement from quiet/resting ventilation to peak expiratory flow rates. The signals of flow, CO2 and O2 are dynamically aligned under software control. A single high pressure pulse of calibration gas is used to perform the alignment and to calibrate the CO2 and O2 gas sensors. Temperature, barometric pressure and humidity sensors are included for dynamic corrections due to varying environmental conditions.  In addition to respiration measurements the system provides standard spirometry data.

The Q-CPX System includes a PC running the renowned ComPAS Software suite for automated cardiovascular fitness measurements.   From configuration of test protocols to test runtime capability, report designing and post data presentation or export for research, ComPAS Software can do it all.

Through use of a highly versatile graphical user interface, ComPAS allows the user to define both the runtime screens as well as final data output. Spirometry can be performed pre, post or during exercise. The runtime test screen is designed to capture data allowing the user to  focus on the subject exercising.

 Exercise runtime studies can include user-configurable “Events”. These may involve dynamic capture of flow volume loops for users wanting to evaluate ventilatory responses to exercise. Other “events” may be the recording manual blood pressures or the taking of ABG or even just an observational note.

 During real-time data acquisition, data are constantly evaluated to ensure that meaningful values are being measured. If a parameter appears to be outside of expected clinical range then an “Alert” is shown. These alerts are based upon script settings and the ranges can be changed by the user if desired.

 Post test report capability is extensive. Report presentations can be designed to allow for any combination of header information (including logos) data format, graph size, order and computer impression.

 For research purposes, a user-configurable exporter is provided which allows for individual data sheets or workbooks to be formatted and exported to Excel.

 Through internet connection, the Q-CPX provides bi-directional communication with Qubit scientists. By invitation we can view the system and assist customers.

 Calibration of the Q-CPX System is fully automated.  A novel algorithm is used to perform flow calibration using a minimal number of strokes with a calibration siringe.  The  set up ot the Q-CPX System is minimal and accuracy is assured.
