Geology laboratory needed for elemental and heavy metals analysis of two ores from a new source including iron ore to >10 ppm, with % or ppm concentrations within 10% or so. I suggest XRF, ICP or a combination. In addition, from another source I have some heavy minerals concentrate and need to know all significant minerals present and their concentrations, including ppm of gold, if any.

FDA cGMP pharmaceutical Laboratory needed for viscosity testing: Magnesium Aluminium silicate. Sample solution: After determining the Loss on Drying, weigh a quantity of Magnesium Aluminum Silicate, equivalent to 25.0 g on the dried basis. Over a period of a few seconds, transfer the undried test specimen to a suitable 1-L blender jar containing an amount of water, maintained at a temperature of 25 ± 2°, that is sufficient to produce a mixture weighing 500 g. Blend for 3 min, accurately timed, at 14,000?15,000 rpm (high speed).
[Note?Heat generated during blending causes a temperature rise to above 30°.]
Analysis: Transfer the contents of the blender to a 600-mL beaker, allow to stand for 5 min, and adjust, if necessary, to a temperature of 33 ± 3°. Using a suitable rotational viscometer equipped with a spindle as specified below, operate the viscometer at 60 rpm for 6 min, accurately timed, and record the scale reading.
For Type IA, use a spindle having a cylinder 1.87 cm in diameter and 0.69 cm high attached to a shaft 0.32 cm in diameter, the distance from the top of the cylinder to the lower tip of the shaft being 2.54 cm, and the immersion depth being 5.00 cm (No. 2 spindle). If the scale reading is greater than 90% of full scale, repeat the measurement, using a spindle similar to the No. 2 spindle but having the cylinder 1.27 cm in diameter and 0.16 cm high instead (No. 3 spindle).
For Type IC, use a No. 3 spindle. If the scale reading is greater than 90% of full scale, repeat the measurement using a spindle consisting of a cylindrical shaft 0.32 cm in diameter and having an immersion depth of 4.05 cm (No. 4 spindle).
For Types IB and IIA, use a No. 2 spindle.
Type IA: 225?600
Type IB: 150?450
Type IC: 800?2200
Type IIA: 100?300
Geology Laboratory needed for ASTM testing: Analys of rock salt (sodium chloride) based on requirements of ASTM D632. Chemical analyses will include sodium chloride purity (%NaCl) and moisture, but sodium ferrocyanide may also be requested. Physical analysis will entail a sieve analysis on the rock salt to determine the particle size distribution.
Food laboratory needed for microbiology and shelf-life testing of refrigerated beverage to be sold at 7-Eleven stores. Product testing is divided into two levels. Level I Testing, which is for pathogenic micro-organisms may be done from composite testing. Composite testing is where all the samples are blended together and then tested as one entity. Since the presence of any microorganisms identified in Level I is prohibited, this is a cost effective and accepted method of determining compliance to Level I standards.
Level II testing covers those microorganisms that can affect freshness, such as yeast and mold and is required for any shelf life up to and including seven days which is the maximum allowable shelf life by 7-Eleven.
Level II testing for spoilage organisms must be done on each product individually at initial (day 1), mid-life (day 4), end of shelf life (day 7), and end of shelf life plus 3 days (day 10).
