DSC data was collected using a TA Instruments DSC Q2000 with an RCS 90 mechanical cooler. TA Instruments’ patented Tzero™ DSC technology, is a revolutionary and fundamentally more accurate way of measuring heat flow. This DSC is equipped with the Refrigerated Cooling System 90 [RCS 90]. The pan was placed in the DSC and a method was executed that first equilibrated the cell at 200 °C and held it isothermally for five minutes in order to fully melt the sample. The maximum rate of cooling depends on the temperature range of your experiment. TA Instruments supplies the following Q Series DSC's. he TA Instruments Q100 Differential Scanning Calorimeter (DSC) is a powerful and versatile thermal analyzer that allows for property measurements on a broad variety of materials from … The TA Instruments PCA is based on a filter photometer design, in which radiation from a high pressure mercury source passes through broadband filter (320- 500 nm as supplied) and then is transmitted to the DSC cell via a one-meter long, 3-mm diameter, dual extended range (250-700 nm) quartz light guide. Through deconvolution of the Total Heat Flow signal, events such as a glass transition masked under an evaporation peak, or the simultaneous occurrence of a cold crystallization with a melt, are easily revealed. SOP for TA Instruments – Discovery DSC RES-02-002-B 3 SAFETY The subsections below outline some of the obvious / major hazards that could exist during the operation of the TA Instruments Discovery DSC, and are divided to bring a level of clarity to such hazards. TA Instrument Discovery Differential Scanning Calorimeter [DSC] 250. It provides significant improvements in baseline flatness, transition resolution and sensitivity. This equation can be further modified to account for pan heat flow effects. Simplified descendant of the original power compensation DSC, and a close relative to DTA (differential thermal analysis) instruments, this DSC is adequate for a measurement of accurate temperature range of a thermal transition. Modulated DSC ® Gain confidence in data interpretation with the help of MDSC ® *, now standard on all Discovery DSC models. 2 DSC Q Series Getting Started Guide ©2001–2004 by TA Instruments—Waters LLC 109 Lukens Drive New Castle, DE 19720 Notices The material contained in this manual, and in the online help for the software used to support this instru- “The TA Instruments DSC 2500 and TGA 5500 will allow Covalent to deliver the most accurate, flexible, and efficient thermal characterization services possible. This configuration can be used for experiments requiring cooling within an operating range of - 90°C to 550°C. The TA Instruments Q Series DSC's are specifically designed to account for those latter heat flows. TA Instruments Q100 features a single-furnace design and heat-flux measurement principle.
