Oxygen	All Ranges	2	PE 2400 CHN Analyzer fitted with an oxygen accessory kit. Direct oxygen analysis can not be determined on inorganic samples or samples containing phosphorous.
Karl Fischer (Coulometric)	0.1 - 1.0 1.0 - 5.0 > 5.0	25 - 50 10 - 20 5	Volumetric Determination Available Under Special Circumstances but must be Quoted by the Lab
Optical Rotation	10° - 20° > 20°	100 10 - 20	Informational Purposes Only
TGA	N/A	5 - 10	Run according to client specific heating conditions Default: 10^o/min. to 300^oC
Ion Chromatography	.05 - 1 100 ppm	5 - 10 25 - 50	If sample limited, check with the lab for specific sample requirements since each ion has different response factors
*Metals Determination:*
Flame AA	.05 - 1 1 - 5	25 - 50 10 - 20	Volatile Elements (e.g. Mercury & Arsenic) quantitated using Cold Vapor AA: $500 Set-up $100/sample
Graphite Furnace AA	1 - 10 ppm .05 - 1	25 - 50 10 - 20	Provides better sensitivity than AA or ICP but can run only one element at a time.
ICP	1 - 10 ppm 50 - 100 ppm	100 25 - 50	Can be used for all metals but response level varies. If sample limited confirm detection limits w/ lab.
ICP-MS	.1 - 1 ppm 5 - 10 ppm	100 25 - 50	In the event that a customer requests two or more elements, where one must be run on the ICP-MS and one could be run on the ICP-OES, all samples will be run on the ICP-MS. We will not split the samples on two instruments. For Osmium there is an additional $500 setup fee.
Micro-Ash	5 - 10	10 - 25	Informational Purposes Only

Analysis	Theoretical Range (%)	Sample Size (mg)	Additional Information
Turnaround Time for all coded with this color is 10-15 Business Days. RUSH is subject to Resource Availability for a 5-7 Business Day Turnaround.
Gas Chromatography	100 ppm	100	Additional methods may be necessary when there are solvent interferences. Solvents that are not part of our standard set require method development and will be conducted on a Time & Materials basis. Costs for the method development efforts typically range from $1,500 to $3,000, in addition to the set-up and per sample charges. * THF & Chloroform coelute and can not be quantitated simultaneously using this method
Solvent List: 1,4-dioxane, Acetaldehyde, Acetone, Acetonitrile, Benzene, Chloroform, Dichloromethane, Diethyl ether, Dimethyl sulfoxide (DMSO), Ethanol, Ethyl acetate, Heptane, Hexane, Isopropanol, Isopropyl acetate, Isopropyl ether, Methanol, Methyl acetate, Methyl Ethyl Ketone (MEK), Methyl t-butyl ether, n-propyl acetate, Tetrahydrofuran, Toluene, Trichloroethylene
Gas Chromatography - Mass Spectroscopy: If no method is provided, QTI will develop a method on a Time and Materials basis. Costs for the method development efforts typically range from $1,500 to $3,000 in addition to the set-up and per sample charges. Analysis is based on electron impact (EI) fragmentation Unknowns are compared to an internal system library

<USP> Analyses: (20 Working-Day Turnaround)
All USP tests will be performed within a 20 working-day turnaround (unless performed on a “Rush” basis or part of a quoted project) “Rush” USP Testing will be quoted on a Time & Materials Basis All non-project related USP test samples must be submitted using a “Request for USP Testing” sheet

Heavy Metals <231> $300 for Single Determination $60 per Re-Ashing	10 ppm 20 ppm	2 grams 1 grams	This test will only indicate whether or not a metallic impurity, that is colored by sulfide ion, exceeds the Heavy Metals limit. Methods I, II, III are listed in the USP (see below). QTI performs Method II as default but can also perform Methods I & III (Call for pricing and requirements.) Substances that typically will respond to this test are lead, mercury, bismuth, arsenic, antimony,tin, cadmium, silver, copper, and molybdenum
Residue on Ignition (ROI) <281> $60 for Single Determination	0.1 - 1	2 - 3 grams	All samples which fail to meet monograph specifications will be re-run at $40 per re-fire.

LOD <731> $60 per Sample $40 each additional drying time		1-2 grams	If it is to constant weight, it will be a minimum of 2 drying times. compendial or Non-Compendial = Listed in USP or Not Compendial = 1 drying time Non-Compendial = At least 2 drying times Constant weight is anything <50mg. We stop once we check and it is <50mg difference from prior drying.
