Supplier: ELECTRON MICROSCOPY SCIENCE
Description: X-Ray Windows are the ideal substrates for x-ray microscopy and x-ray spectroscopy techniques. State-of-the-art manufacturing and expert engineering allow for competitive prices of these windows. Made in the USA, these X-Ray windows are entirely plasma cleanable to remove organic contamination. Flat, uniformly deposited films provide consistent backgrounds with low field-to-field variability and high x-ray transmission.

Supplier: Electron Microscopy Sciences
Description: MAC has developed multi-element blocks of reference materials suitable for the compilation of a reference library of Auger sensitivity factors when used with the Auger Electron Microscopy (AES). (Auger electron: one of the electrons ejected from an atom as a result of the internal conversion of its own X-ray in the auger effect. Auger effect: a process in which an atom singly ionized by emitting one electron with energy in the X-ray range instead of emitting the usual X-ray photon on recovery undergoes a transition in which a second electron is emitted).

Supplier: MP Biomedicals
Description: Ammonium sulfide solution (aqueous ammonium sulfide) is a 20% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by X-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED). Its potential as an alternative to hydrogen sulfide for the transformation of activated amides to thioamides by thiolysis has been investigated.The reaction of ammonium sulfide with 3-hydroxy-2-butanone over a range of temperature has been reported to form various flavor compounds.
Catalog Number: (76439-544)
Supplier: ELECTRON MICROSCOPY SCIENCE
Description: Suspended germanium provides a unique calibration standard for x-ray energy dispersive spectroscopy. Since Ge is not typically found in TEM columns, the calibration samples provide a material that cannot be mistaken for instrument components and their signal peaks. The regime in which system peaks normally occur (2 to 9 keV and 11 to 20 keV) is devoid of peaks from the Ge.


Catalog Number: (H-4902.0001BA)
Supplier: Bachem Americas
Description: Anticoagulant and antithrombotic peptides. Please see also the product family 'Hirudin Fragments and Analogs', the inhibitors N-1065, N-1215, N-1260, N-1565, and N-1970, and the anticoagulant anisindione, Q-1085.
