Description

THIS IS FOR INFORMATIONAL PURPOSES ONLY. Under the authority of FAR 13.106, the USDA FS Northern Research Station - 07, Vermont intends to award to Campbell Scientific Inc. on a sole source basis, a Firm Fixed Purchase Order (PO) for a Differential Thermal Analysis (DTA) System - components to construct a system in house.

A differential thermal analysis (DTA) system is a specialized laboratory apparatus used for measuring plant cold hardiness and designed to detect cellular-level freezing events within plant tissues. The system works in conjunction with a protocol of sample handling, manipulation of temperature via a programmable cold chamber, and a freezing detection system (DTA):

Sample preparation: Plant tissues, such as floral buds, are carefully collected and prepared for analysis. The samples are often placed in small aluminum foil packets or directly on thermoelectric modules. Temperature control: The system includes a temperature-controlled chamber or cooling plate that can lower the temperature at a controlled rate, typically mimicking natural freezing conditions. Thermoelectric modules: The samples are placed on thermoelectric modules (TEMs) or thermocouples that can detect minute temperature changes. Multiplexers: A series of multiplexers are needed to monitor many TEMs. Reference sample: A reference sample, usually an inert material that doesn't undergo phase changes, is placed alongside the plant tissue samples for comparison. Cooling process: Plant tissue and reference samples are exposed to gradually decreasing temperatures in a cold chamber, often at a rate of 2-4°C per hour, to simulate natural freezing conditions. Exotherm detection: As plant tissues freeze, they release heat (exotherms). The DTA system detects these exotherms as temperature differences between the plant tissue sample and the reference. Data acquisition: A logging system continuously records the temperature data and identifies exotherms, which appear as pea...
