(†) Optional elements, see Code 4A

Notes:

Code 4A - Both the exploration and research grades are determined by INAA. A minimum sample weight of 2 g is recommended.  REE chondrite plots are provided at no charge with the research grade or at $1.50 per sample for the exploration gradeFor elements indicated with †(Code 4A RES/MS) by fusion ICP/MS, add $34.25.

Codes 4B, 4B2-STD, 4B2-RESEARCH, 4LITHO, 4LITHORESEARCH - Actlabs has developed a lithium metaborate/tetraborate fusion ICP Whole Rock Package Code 4B and a trace element ICP/MS package Code 4B2 which is unique for scope of elements and detection limits.  The two packages are combined for Code 4Litho and Code 4Lithoresearch.  The quality of whole rock data in Code 4B meets or exceeds quality of data by fusion XRF Code 4C, the old standard in whole rock analysis. The fusion process ensures total metals particularly for elements like REE in resistate phases.  (This may not be the case for acid digestions, particularly for heavy rare earths and other elements contained in refractory minerals like zircon, sphene, monazite, chromite, gahnite and several other phases.  If refractory minerals are not digested, a bias may occur for certain REE and HFSE with acid digestions).  Quality of data is exceptional and can be used for the most exacting applications.  The trace element package by ICP/MS, Codes 4B2-STD or 4B2-RESEARCH, on the fusion solution provides research quality data whether using standard or research detection limits.  Eu determinations are semiquantitative in samples having extremely high Ba concentrations (greater than 1%).  This package is intended primarily for unmineralized samples.  Mineralized samples can be analyzed, however, data may be semiquantitative for chalcophile elements (Ag, As, Bi, Co, Cu, Mo, Ni, Pb, Sb, Sn, W and Zn).  When quantitative values for the chalcophile elements are required on mineralized samples, please indicate as Code 4B2-STDQUANT, 4B2-RESEARCHQUANT, 4LITHOQUANT or 4LITHORESEARCHQUANT, and a surcharge of $19.75 per sample will apply.  A minimum sample weight of 5 g is required.  Elements with (+) are available (Code 4B1) for an additional $10.25 per sample.  Those indicated with (++) are available by INAA (Code 4B-INAA) for an additional $18.25 per samplePlease add 0.5 to 30 g depending on sample size you prefer to analyze for Au with this option.  Values on replicates and standards are provided at no cost, as are REE plots. 

Code 4C - The tried and true fusion XRF whole rock package.  Samples containing high barite or high sulphide (greater than 1%) should be analyzed with Code 4B.  A minimum sample weight of 3 g is required. We reserve the right to change analytical method to Code 4B if required by the sample composition.

Code 4C1 - This XRF pressed pellet method requires a minimum sample weight of 6 g.  The XRF pressed pellet method is only suitable for low metal content of below 1% for each element listed.

Prices: 1st element - $12.25; each additional - $4.00; ** lot - $22.00; * lot - $22.00.  Each element not in * or **, add $4.00 per element.

Code 4E - This unique package uses ICP, INAA, ICP/MS and XRF technologies to completely characterize geological samples.  Two different grades of analysis (exploration and research) are provided depending upon your requirements.  This package is not suitable for analyzing concentrates or mill products.  A minimum sample weight of 5 g is required. 

Code 4E Options

• Ga, Pb, Sn, Nb and Rb (Code 4E-XRF) indicated by (***) by Pressed Pellet XRF add $22.00.  This package can be added to Code 4E exploration or Code 4E research (please add 6 g of sample).

• The Code 4E ICP/MS add-on option (detection limits indicated by +++) can only be added to Code 4E research grade at an additional cost of $36.50.

• Any selections from Code 4F can be added to Code 4E exploration or research 

Code 4F - Other analyses associated with WRA (can be added to any Code 4 package).  Add 1 gram for each option chosen.
