New CRMs for 2017
As a challanging year draws to a close we’d like to wish all our respected customers a safe and happy festive season and more prosperous 2017. We are deeply indebted to the many laboratories for their continued support to our OREAS certification programs - thank you, your collaboration is truly appreciated.

Over 200 tonnes of OREAS CRMs in stock

Throughout 2016 we’ve been beavering away at our inventories to ensure our valued customers have continuity of supply. This year, previous stock records have been broken with over 200 tonnes of OREAS CRMs ready to ship. Prominent amongst this is our largest batch ever produced: 6.4 tonnes of OREAS 253 (1.22ppm Au). As with all OREAS gold CRMs, homogeneity is guaranteed and demonstrated at the one gram level.

Holiday closure period

ORE P/L will close for a short period over the holiday season but a skeleton crew will be on hand to dispatch urgent orders on certain dates.

To avoid delays, please submit your orders by Monday 12th December to ensure your CRMs are dispatched prior to year’s end.

Our manufacturing and technical divisions will close briefly over the holiday break (see dates below) but Sales staff will monitor email enquiries regularly and can dispatch orders on 29th December and 5th January during the business closure period shown below.

We close on: Thursday 1pm, 22nd December, 2016
We reopen on: Wednesday, 11th January, 2017

Major & Trace element data added to 36 CRMs

The Certificates and their associated DataPacks for 36 pre-existing OREAS CRMs have been updated with over 72 new indicative (uncertified) values for major and trace elements determined by borate fusion XRF and laser ablation ICP-MS.
This will further extend their utility and surpasses ISO Guide 31 recommendation in regard to, "the approximate composition of the material should always be stated."

Technical Note - Rotary Splitting

This techical note documents the capability of ORE’s new High Frequency Rotary Splitters to produce fit for purpose homogenous chip CRM’s from heterogeneous bulk commodities. The splitters are prototypes (patent pending) and are designed and built in-house. They have the capacity to process batches in excess of 10 tonnes and operate at 280 (large splitter) and 420 (small splitter) doses per minute.



The first stage splitter contains 16 cells and is capable of splitting a 20-plus tonne sample. The secondary unit contains 24 cells and is capable of splitting 50-100kg samples down to 1-2kg (as required). These splitters are best-in-class and have successfully split multiple tonne batches of bulk commodities (iron ore, copper ore, bauxite, basalt, rhyodacite, etc.) of minus 10mm material into 2kg units. The round robin certification and homogeneity results show outstanding repeatability between the 2kg units, comparable with repeatability seen in pulp CRMs.

Industry support to innovative technologies

ColdBlock

ORE P/L is proud to support innovative analytical techniques like ColdBlock Digestion Technology. Developed in Canada, the method shows outstanding promise as a safe and rapid alternative to established digestion methods. The sample particles are directly heated by the infrared rings and the acid remains cooler due to a cooling mechanism built into the base. This leads to short cooling times, minimal acid consumption and generally, only phosphoric acid is required.

Lab at Rig® - pressed pucks for pXRF

In support of the Lab-at-Rig® collaboration, ORE P/L has helped 'field-test' Reflex's prototype 30 tonne manual sample press. This hydraulic press can make our CRMs into 'pucks' which greatly enhances the reading sensitivity of handheld portable XRF devices. ORE P/L has donated CRM pucks from our range of OREAS SuperCRMs® made during the field testing trials. These pucks are helping CSIRO scientists Steven Tassios and Yulia Uvarova develop LIBS (laser-induced breakdown spectroscopy) calibrations. Steven says, "LIBS is an emerging analytical technique directly applicable to rapid geochemical analysis. In fact, there’s one bolted onto the Curiosity rover that’s running around Mars at the moment!"
Reflex's 15T hydraulic press can produce pressed puck CRMs similar to those pictured.
