DISCOVERY SA WEIGHING PERFORMANCE Low DRIFT High CAPACITY Most ACCURATE DATA At the core of every new Discovery SA is the proprietary Tru-Mass™ Balance. The Tru-Mass Balance system is actively temperature controlled for high sensitivity in every laboratory environment, delivers the highest resolution to accurately measure humidity sorption on the most challenging samples, and has ultra-low drift (Tru-Mass) for weight accuracy. Compared to competitive devices, the Discovery SA delivers higher weighing resolution and better baseline stability at all operating conditions. This guarantees industry...

The Tru-Mass™ balance provides a weighing resolution of 0.01 Mg over a 1000 mg weighing range. The sophisticated symmetrical balance design and efficient temperature control provide accurate weight measurements under all operating conditions. The Discovery SA features isothermal baseline stability of ±0.25 |_ig over 24 h and low drift of ±1 pg over the temperature and humidity controlling range. With industry leading weighing performance capabilities, the Discovery SA can analyze of the most challenging samples with accuracy and ease.

TECHNOLOGY WIDEST HUMIDITY CONTROL RANGE Precise Wide-Range Humidity Control for Reliable Sorption Analysis The precise humidity control of the Discovery SA in combination with its industry leading weighing performance allows you to measure, analyze and optimize the water sorption properties of your sample material. Balance Evaluating the sorption properties of advanced materials requires accurate control of the humidity from completely dry conditions to almost condensation. The Discovery SA provides humidity control from 0% RH to 98% RH in the entire temperature range from 5°C to 85°C. Only...

SOPHISTICATED TECHNOLOGY Providing ACCURATE AND REPRODUCIBLE HUMIDITY CONTROL 16 Humidity Control Microcrystalline cellulose (MCC) is a material with well characterized humidity sorption properties. In the plot on the left, humidity sorption data on MCC measured with the Discovery SA are plotted over RH. The red symbols in the plot are published, certified reference values from a COST 90 inter-laboratory test. The data measured with the Discovery SA are in agreement with the certified values within their confidence intervals over the whole RH range. The excellent agreement found between the measured...

TECHNOLOGY RELIABLE AUTOMATION BOOSTS PRODUCTIVITY Improved Productivity in Sorption Analysis The integral Discovery SA autosampler features a programmable multi-position sample carousel that permits automated analysis of up to 10 samples using semispherical quartz (or metalcoated quartz) crucibles and 25 samples using the optional tray with platinum or sealed aluminum pans. The design provides smooth and efficient loading and unloading of the sample pan without disturbing the balance. All aspects of sample testing are automated and software controlled including pan taring and loading, sample...

AUTOMATION facilitates laboratory WORKFLOWS and increases RELIABILITY The Right Sample Pan for your Sample Material Semispherical quartz, metal-coated quartz (180 μL) and optional platinum (100 μL) sample pans are available for use with the Discovery SA.The former are commonly used in sorption analysis because of their large volume, anti-static capabilities and open design, allowing good gas-sample contact and fast equilibration. Platinum pans are generic for TGA analysis of most materials, provide a good contact between sample and gas and can improve productivity with the 25-position autosampler...

TECHNOLOGY GAS BLENDING Discovery SA Sample Accurate Control of CO2 Concentration and Humidity for Assessment of Carbon Capture Materials A Blending Gas Dosing Module (Blending GDM) can be used with the Discovery SA allowing for automated blending of CO2 into the humid carrier gas flow. The Blending GDM is an external accessory with two gas inlet ports that, when connected to the auxiliary gas port on the SA gives the user a total of two gases (CO2 and N2) and humidity to control. The added blending capability allows for SA experiments to be carried out in a humidity-controlled atmosphere where...

GAS BLENDING and HUMIDITY CONTROL providing FLEXIBILITY to assess CARBON CAPTURE MATERIALS 35 a sorption experiment with ramped of stepped humidity is performed. In this example humidity sorption on a microporous activated carbon is measured at different CO2 concentrations. In the diagram to the right the humidity uptake from a pure N2 carrier gas is compared to the uptake measured when 10% or 20% CO2 were blended in the carrier gas. As the general type III shape of the humidity isotherms remains unchanged, the water sorption is reduced with increasing CO2 concentration in the carrier gas.This...
