Application of the Agilent 7900 ICP

2014/5/30Metrology Institute of Japan (NMIJ). High purity reagents 68% HNO 3 and 36% HCl (Ultrapur-100 grade) were purchased from Kanto single element standards (SPEX Certiprep). Method building The Method Automation function or "Method Wizard" function of

Community standards for open cell migration data

To demonstrate the application of the CMSO standards we applied them to the study by Masuzzo et al. [], which proposed an end-to-end software solution for the visualization and analysis of high-throughput single-cell migration experiments.

Reference materials for stable isotope analysis

Hydrogen isotope working standards are currently calibrated against VSMOW2 and SLAP2 but are still reported on the scale defined by VSMOW and SLAP relative to VSMOW. Additionally, Greenland Ice Sheet Precipitation (GISP) δ 2 H has been measured to high precision in multiple labs, but different analytical facilities disagree on the value.

Tensile Properties of Commercially Pure, High Purity and Ultra High Purity

high-purity, and ultra-high-purity) were characterized at different strain rates in the framework of an international Round-Robin involving four laboratories (BAM, IMR-TU, NIST, and SCK•CEN). The test results were collected and analyzed by NIST, and are presented in this Technical Note.

Phosphoric acid

Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H 3PO 4. It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions

Silicon Wafer Production

Silicon is the second most abundant element in the earth's crust (oxygen is the first). It occurs naturally in silicate (Si-O containing) rocks and sands. The elemental silicon used in semiconductor device manufacture is produced from high purity quartz and quartzite

Organic Standards Archives

High-Purity Standards offers multi-component Certified Reference Materials for a variety of EPA and ASTM methods. All products come with an ISO 17034 Certificate of Analysis which includes concentration values verified against second source Certified Reference Materials and a weight report traceable to NIST.

Germanium

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms

Standard Solution SRMs Provide Traceability for

For decades, NIST has provided the SRM 3100 series single-element standard solutions. The certified values are traceable to the International System of Units (SI), enabling users to establish traceability of their measurement results to the SI. Commercial CRM producers utilize the SRMs to establish traceability of their certification results to the SI. Recent improvements in the SRM 3100
