Retainers for Ultra High Vacuum Compatible Micro and Macro Analysis Standard for Surface & X-ray Analysis (No standards)

UHV (ultrahigh vacuum) compatible (10-10 torr)
Suitable for spectral and intensity references for EDS, WDS, EPMA, Auger, XPS, ESCA, etc.
Custom and standard reference material configurations are available
Rectangular or circular retainers holding from 6 to 37 reference standards
Retainers machined from SS304
Custom mounting bases available

Analysis accuracies of 1-2% (relative) are possible only when appropriate standards are used. UHV systems cannot accept commonly available standard sets because of outgassing of mount materials and degradation from electron beam heating. The use of bakelite, plastic or epoxy embedded standards under UHV conditions have prevented accurate analysis. These inaccuracies are caused by compromised vacuum levels and contaminated reference standards. Also, standardless techniques give no indication that some elements may not be accounted for or are present in an oxide phase.

Reference standards supplied with the UHV-EL, which contain only UHV compatible materials, can be used to characterise the transmission of the electron energy analyser, determine peak shapes, resolution, energies and sensitivity factors.

Since generalised sensitivity factors cannot be used with a reasonable degree of accuracy, even for the same instrument model, it is necessary for these factors to be determined for each unique instrument, on a continuing basis. Conditions will change over time because of peak shift, amplifier settings and spectrometer tolerances.

Custom Ordering Information for UHV-EL Standards

Construction and Design
The retainer is precision machined from stainless steel 304. Each retainer has holes machined with a 0.13mm boss at the top. All reference standards are precisely referenced within 0.13mm of the top surface. This recess protects the reference standard surfaces from contamination and scratching and also minimizes the possibility of X-ray fluorescence from the retainer. The reference standards, which are of various thicknesses, are retained by SS304 clips which are inserted from the back of the mount. The round UHV-EL-37 is laser engraved to assist in locating the desired reference standard using electron

Reference standards are individually sized and polished according to the properties of the material. Cross contamination and smearing is avoided.

If a reference standard surface gets roughened from excessive ion beam sputtering or is too highly oxidised, it can be easily removed and replaced in your laboratory. Tools and clips are provided. If bulk materials are not available for some reference standards, powders are used. They are consolidated with silver flake and the powder grains metallographically polished. Many insulators prepared this way are sufficiently conductive for X-ray and Auger analysis without carbon coating; all minerals and glasses are coated with ~20nm of carbon. The silver can be used for reference when determining sensitivity factors.

Custom Preparation
Your materials may be inserted into one of the retainers described using careful techniques. Electron beam X-ray techniques and reference standards - which are charge sensitive - can be carbon coated. All nonconductive minerals and glasses are coated with ~20nm of carbon.

Shipping
UHV-EL-37 circular retainer reference standards are shipped in a VACU-STORR container. It is optional for other configurations or custom orders.

Certification
The purity or composition of each reference standard is certified by the manufacturer. The SRM classes and certified alloys are NIST traceable, please see information on Reference Standards and Alloys below.
