  • Quartz particles are Certified Reference Materials useful as calibrants and reference materials for particle analysis instruments and techniques requiring samples with a wide size distribution. They are useful for evaluating laser diffraction and electrical resistance analyzers, and for calibrating sieve openings. These standards were prepared under the sponsorship of the Community Bureau of Reference (BCR), the standards bureau of the European Common Market, and executed by laboratories in Germany, Italy and the United Kingdom. Mined in Fruechen, West Germany, the quartz is mostly silicon dioxide with trace amounts of iron (Fe), titanium (Ti), sodium (Na) and calcium (Ca). The chemical composition was characterized by using hydrofluoric acid dissolution, then analysing the residue. Sodium and calcium contents were determined by flame photometry. Iron and titanium were determined using spectrophotometric techniques. Density was determined by pyknometer and is approximately 2.6 g/cm3. BCR 66, 67, 69 and 70 were calibrated by gravimetric sedimentation, and BCR 68 and 130 by a sieving technique. The samples were also analyzed by TEM, electrical sensing zone, sieving and several sedimentation methods. A continuum of the weight distribution is provided for each sample. Results and methods are summarized in two detailed reports: Certification Report on Reference Materials of Defined Particle Size for BCR 66 through 70, and Reference Materials of Defined Particle Size for BCR 130. Both reports are included with the kit. (We will also add the appropriate report to an order of any 6 or more individual items.) Each individual bottle of the quartz reference materials is accompanied by a Certificate of Measurement, which outlines measurement methods, chemical analysis data and instructions for use.

They can be dispersed in aqueous media with the aid of a small amount of surfactant, or in lower alcohols, such as methanol and ethanol. Some dye extraction will result when the particles are suspended in pure alcohols, but will be minimal. Other organic solvents, such as ethers or chlorinated hydrocarbons, should be avoided because they will swell the particles and completely extract the dye.

The product line consists of uniform particle sizes between 50 and 500 microns in either red or black color. The microspheres are made from cross-linked polystyrene divinylbenzene (PSDVB) copolymer and can be stored at room temperature. They can be dispersed in aqueous media with the aid of a small amount of surfactant, or in lower alcohols, such as methanol and ethanol. Some dye extraction will result when the particles are suspended in pure alcohols, but will be minimal. Other organic solvents, such as ethers or chlorinated hydrocarbons, should be avoided because they will swell the particles and completely extract the dye. Chromosphere T product include a Certificate of Calbration and Traceability. Typical applications include: • Reference or calibration materials • Testing of filtration media and systems • Vial and container cleaning evaluations • Flow tracing and fluid mechanics • Contamination control • Sedimentation processes • Calibration of injection devices • Pharmaceutical manufacturing control
  • were developed for use as reference or calibration materials and in applications where a high visual contrast is desired.
