Microtrac's Nanotrac 250 Particle Size Analyzer
Description:
Uses a reference beam and backscatter optics to insure minimum penetrate of light into the sample. Particulate samples suspended in liquid. Range of
size measurements from 0.8 nm to 6.5 microns.
Features:
- Alignment never needed
- Compatible with any organic solvents and most acids/bases as suspending liquids
- No moving parts and simple design, meaning no maintenance and reliable data
- Uses Mie scattering calculations for spherical particles and proprietary modified Mie scattering calculations for non-spherical particles
- Avoids multiple wavelength absorption issues
- Typical analysis time is 15-30 sec.
- &060;3 ml per sample standard cell or as small as 0.1 ml with the small cell option
- Measures monomodal, multi-modal, broad and narrow size distributions automatically without pre-selecting special programs

Micromeritics Gemini 2360 Surface Area Analyzer
Description:
An easy to use, fully automatic, single- or multi-point surface area analyzer. Once an analysis is started, data are collected, calculations are
performed, and results are displayed without further operator intervention. Frequent calibrations associated with presently available flowing-gas
systems are not required.
Features:
- Single-point BET surface area
- Multi-point BET surface area
- Requires only pure nitrogen as the analysis gas, even for most low surface area samples
- Requires no flow regulator, gas mixer or mixed gases to operate
- Usually no need for krypton gas
- Surface areas as low as 0.01 m2/g are easily determined with excellent precision

Micromeritics AccuPyc 1330 Helium Pycnometer
Description:
An easy-to-use, fully-automatic gas displacement 1-cc pycnometer. It can also be used to analyze samples with volumes of 0.1 cc and smaller by using
the 0.1-cc sample instead of the 1-cc sample cup. Once an analysis is initiated, data are collected, calculations are performed, and results are
displayed without further operator intervention.
Features:
- Increases the precision of analysis results by reporting data from five consecutive runs that are within a user-specified tolerance
- Allows early termination of analyses, thereby decreasing the number of runs needed for accurate results
- Reproducibility of absolute density is + 0.01% when sample volume nearly fills the sample holder
- Accuracy is within 0.03% of indicated volume plus 0.03% of the nominal full-scale sample chamber volum

Micromeritics Sedigraph 5100 Particle Size Analyzer
Description:
Fully automatic analyzer for measuring particle size and size distribution. It contains an internal fixed-position X-ray source/detector assembly and
a vertical cell movement assembly. It incorporates a complete system for circulation of sedimentation liquid and particle sample mixture between the
cell, the external mixing chamber, an external rinse liquid container, and an external waste container.
The analyzer provides a wide range of graphs and tabular reports of results, including cumulative mass percent finer (or coarser) vs. diameter (or
radius), number population vs. diameter, surface area population vs. diameter, log probability graph, statistical process control charts, etc.
Features:
- A sliding transparent door provides convenient observation of, and access to the temperature-controlled analysis compartment
- Determines the size of all particles in terms of the equivalent spherical diameter
- Cell elevator allows measurement of a wide range of particle sizes without having to wait for the smallest to settle the entire length of the cell
- Mechanical shutter blocks the X-rays if the transparent door is opened

TA Instruments SDT Q600 TGA/DSC With Mass Spectrometer
Description:
Simultaneous measurements of weight change (TGA) and differential heat flow (DSC) on the same sample. It can be used for a broad range of samples.
Temperature range is from 25C to 1500C. Ability to analyze two TGA samples simultaneously. The instrument is connected to a mass spectrometer to
analyze the composition of a gas mixture.
Features:
- Horizontal dual-balance mechanism that supports both TGA and DSC measurements
- Less drift, thereby improving weight measurement accuracy and precision
- High sensitivity, accuracy and precision in detecting very small weight changes
