- Description
- Statement of Work: We need a gas exchange system that is identical to the existing LI-COR 6400 systems that are currently used in our research laboratories. We need system that will be used to investigate the responses of leaf photosynthesis, as measured with both gas exchange and chlorophyll fluorescence, to a range of environmental conditions. The use of this equipment will help us to determine the impact of various stress events, genetic modifications, environmental changes, or other effects on plant photosynthesis. The specifications are as follows: System: Type: Absolute, open path, non-dispersive infrared gas analyzer. Range: 0-3000 µmol mol-1. Bandwidth: 10 Hz. Signal Noise: Typically 0.3 µmol mol-1 peak-to-peak at 350 µmol mol-1 with 1 second signal averaging; 0.8 µmol mol -1 maximum. With 4 second signal averaging, signal noise is typically 0.2 µmol mol-1 peak-to-peak. Accuracy: Maximum deviation: ± 5 µmol mol-1 from 0 to 1500 µmol mol-1 ± 10 µmol mol-1 from 1500 to 3000 µmol mol-1. Sensor: Solid state. Minimal sensitivity to motion. Orientation Sensitivity: ± 1 µmol mol-1 at 350 µmol mol-1 from any orientation. H2O Analyzer Type: Absolute, open path, non-dispersive infrared gas analyzer. Range: 0-75 mmol mol-1, or 40°C dew point. Bandwidth: 10 Hz. Signal Noise: Typically 0.04 mmol mol-1 peak-to-peak at 20 mmol mol-1 with 1 second signal averaging; 0.06 mmol mol-1 maximum. With 4 second signal averaging, signal noise is typically 0.03 mmol mol-1 peak-to-peak. Accuracy: Maximum deviation: ± 1.0 mmol mol -1 from 0-75 mmol mol-1. Temperature Operating Temperature Range: 0°C to 50°C. Optical Housing Block and Air Temperature: Sensor Type: 3-wire thermistor. Range: -10 to 50°C. Accuracy: Maximum error < ± 0.5°C. Typical Error: < ± 0.25°C. Temperature Control: Leaf chamber can be heated or cooled ± 6°C from ambient. Control Range: 0 to 50.0°C. Set point Resolution: 0.2°C. Leaf Temperature Thermocouple: Type: E. Range: ± 50°C of reference. Reference: Optical housing block thermistor. Accuracy: ± 10% of T difference between sample and reference junctions with amplifier zeroed; typically < 0.2°C. Output RS-232: Hardwired DTE. Expansion Slot : Supports either Compact Flash or Ethernet card adapter. Compact Flash Card: Industrial Grade (included) Ethernet Card Adapter: Type 1 CF Ethernet card, 10/100 Mbps (included) Air Flow Flow rate: 0 to 700 µmol s-1 with 6400-01 CO2 injector and 150 to 1000 µmol s-1 without CO2 injector. Pressure Pressure Range: 65 to 110 kPa absolute. Accuracy: ± 0.1% of full scale. Resolution: 0.002 kPa. Signal Noise (peak-to-peak): 0.002 kPa typical. System Console Processor: 400MHz Intel XScale Memory: 128 MB RAM for operation; 64 MB flash memory for data storage. Display: Adjustable contrast, backlit, 8 line x 40 character (240 x 64 dot) LCD graphic display. Keyboard: Full ASCII keypad, sealed from dust and moisture with membrane overlay. Power Requirement: 10.5 to 15 VDC; 4A maximum (current draw dependent upon system operation). < 10A momentary peak. 6400-01 CO2 Injector CO2 Mixing Range: < 50 µmol mol-1 to > 2000 µmol mol-1. Operating Temperature Range: 0-50°C. CO2 Source Assembly: Type: 12g pure liquid CO2 cylinder. Lifetime: 8 hours after activation regardless of use. CO2 Tank Connector Block: Minimum Pressure: 1250 kPa (180 psig). Maximum Pressure: 1500 kPa (220 psig). Usage Rate: constant at ~10 sccm. Light Measurement PAR Internal and External Chamber Sensors: Range: 0 to > 3000 µmol mol-1. Resolution: < 1 µmol mol-1. Calibration Accuracy: ± 5% of reading, traceable to NIST. 6400-02B LED Light Source Output Range: 0 to 2000 µmol m-2 s-1 at 30°C. Minimum Fraction Blue: 5% (photon basis).
