Remarks:
The BXMG-3 is a washed bauxite sample originating from Monjolo region, located in Minas Gerais State, Brazil. The raw material was oven-dried, crushed and pulverized to pass a 0.150 mm screen and then homogenized. A unit of BXMG-3 consists of 120 g of powdered ore, packaged in a glass bottle. Analyses must be performed on samples that have been previously dried for at least 16 h in an oven controlled at 105 ± 2 ºC. The contents of the bottle should be mixed (by rolling the bottle) before taking samples. The mass of samples used for analyses should be greater than the minimum size indicated for certified and indicative property values. Avoid prolonged exposure to air. Tightly recap the bottle after sampling. The material should be stored at ambient temperature in a dry place. This material contains fine mineral particulate. Avoid dispersion of, exposure to dust by inhalation, eye contact or skin contact. Dispose residual material in accordance with regulations pertaining for inorganic chemical and mineralogical waste.

Intended Use:
This reference material is intended for use in calibration of a measurement system, assessment of a measurement procedure, quality control and value assignment to materials with similar matrices.

Remarks:
The CRM is a set of three sealed NMR tubes (10 mm O.D.) placed in a cardboard box. The tubes contain one reference ethanol (L, M or H) to which tetramethylurea (TMU) ERM-AE003 and hexaflurobenzene (HFB) were added as internal standard and NMR lock substance respectively. The tubes are sealed under an atmosphere of argon. *** For more information see https://crm.jrc.ec.europa.eu/p/ERM-AE200 *** Additional keywords: SNIF-NMR authenticity OIV-MA-AS311-05 SNIF NMR/RMN FINS

Intended Use:
The material is used for standardisation (performance verification) of NMR spectrometers. It is recommended to routinely run the spectra of two of the reference ethanols which have (D/H)I values at the two ends of the range of isotopic ratios usually determined in the laboratory. Weekly calibrations are appropriate to detect any potential drift in the overall stability of the spectrometer.
