The iFL Integrated Fluorometer and Gas Exchange System combines climate-controlled gas exchange measurements and advanced chlorophyll fluorescence analysis.
This third edition’s user-friendly design includes several pioneering features such as leaf absorptance measurement, and white LED lighting that allows chloroplast migration to occur. It is also the first to offer humidity control above ambient, and the first to include pre-installed protocols, such as the Laisk protocol, the Kok protocol, the Yin protocol, the Flexas chamber leakage protocol which streamlines complex research tasks and enhancing measurement accuracy.
KEY FEATURES
• Climate-controlled gas exchange:
Equipped with high-precision CO₂ and H₂O analyzers. The measuring range of the CO₂ analyzer is 0~3100µmol·mol⁻¹, and the H₂O analyzer is 0~75mmol·mol⁻¹. It can precisely regulate the leaf chamber flow rate at 0~1400µmol·s⁻¹. The leaf chamber pressure control range is 0~0.1 kPa with a control resolution of 1.0 Pa. The pressure sensor has a measurement range of -2~2 kPa and a resolution of 1.0 Pa. It also supports precise regulation of leaf chamber humidity from 0 to 90%RH and CO₂ concentration from 0 to 2000µmol·mol⁻¹, providing stable and consistent experimental conditions for reliable gas exchange analysis.
• Advanced chlorophyll fluorescence:
Adopting the pulse-modulated fluorescence technology of Opti-Sciences to measure quantum yield, electron transport rate and various quenching parameters. The instrument modulation frequency covers 1Hz~250kHz, the saturation flash output ranges from 0 to 16000µmol·m⁻²s⁻¹, and the far-red light output ranges from 0 to 20µmol·m1⁻²s⁻¹, which greatly improves the accuracy and application range of fluorescence detection.
• Pre-installed experimental protocols:
Automate key procedures including Laisk, Kok, Yin and Flexas protocols, simplifying complex experiments and ensuring repeatable accuracy.
• White optical LED light source:
Delivers consistent and stable spectral output with light intensity control ranging from 0 to 3000µmol·m⁻²s⁻¹, which is essential for accurate chloroplast migration and non-photochemical quenching measurement.
• Comprehensive leaf absorptance measurement:
An RGB sensor is used to accurately measure leaf absorptance, ensuring the accuracy of fluorescence and gas exchange measurements.
• Walk-in automatic operation:
Supports full automation of extended protocols, allowing researchers to start experiments and retrieve results later without manual intervention.
• Multi-flash frequency correction:
Integrates the advanced Loriaux (2013) correction method to ensure high precision of fluorescence measurement under high-intensity light conditions.
• User-friendly interface:
Equipped with a color touch screen and intuitive menu navigation, simplifying setup, operation and data review.
• Powerful data storage and connectivity:
The device is configured with ≥2GB RAM and 8GB flash memory. It can store large datasets internally and via removable SD cards, and supports convenient USB data transmission and configuration.
