Certificate of Analysis Details
Components of SEASTAR™'s Certificates of Analysis: (also available in pdf file format)
1) Product Number: consists of the Product Grade combined with the Product Type. For example, BA-01 refers to BASELINE® quality Product Grade, Nitric Acid.
a. Product Grade (IQ or BA)
IQ - Instrument Quality
BA - BASELINE®
b. Product Type: please note that the Product Type, in the Product Number always uses 2 digits as opposed to the Product Type for Lot Number (see 2a below).
01 - Nitric Acid
02 - Perchloric Acid
03 - Sulfuric Acid (Sulphuric Acid)
04 - Hydrochloric Acid
05 - Hydrofluoric Acid
06 - Acetic Acid (Acetic Acid, Glacial)
07 - Ammonia Solution (Ammonium Hydroxide)
08 - Hydrobromic Acid
09 - Water
17 - Hydrogen Peroxide (Hydrogen Peroxide Solution)
2) Lot Number: Consists of the Product Grade, Product Type and date. For example, the Lot Number 1205040 is Nitric Acid, BASELINE® quality, the year 2005, the 4th month and the first lot for that month.
a. Product Type:
1 - Nitric Acid
2 - Perchloric Acid
3 - Sulfuric Acid (Sulphuric Acid)
4 - Hydrochloric Acid
5 - Hydrofluoric Acid
6 - Acetic Acid (Acetic Acid, Glacial)
7 - Ammonia Solution (Ammonium Hydroxide)
8 - Hydrobromic Acid
9 - Water
17 - Hydrogen Peroxide (Hydrogen Peroxide Solution)
b. Product Grade (IQ or BA)
1 - Instrument Quality
2 - BASELINE®
c. Year: YY - Numeric, 2 digit, i.e. 05 for 2005
d. Month: MM - Numeric, 2 digit, i.e. 04 for April
e. Version: N - Numberic, 1 digit, i.e. 0 for the first, 0, 1, 2, 3, …
3) Release Date: The date the Certificate of Analysis was generated.
4) Expiry Date: The date when the Certificate of Analysis expires. SEASTAR™ guarantees all of its product's certified integrity for three years if unopened and sealed under the following conditions:
a. Stored at room temperature, maximum range 150C (590F) to 250C (770F).
b. Minimum exposure to light.
c. For limited time, storage/transport temperature range 50C (410F) to 350C (950F)
d. Upon opening the product, the product's integrity will depend on proper handling and exposure to contaminants. The product has been bottled under Class 100, or better, clean room conditions, to maintain the certified quality it should be used under these conditions.
NOTE: under these conditions, even after the expiry period, the products will not degrade. After extensive testing SEASTAR™ has found that most analytes will remain within the specified levels and the product is still usable.
PRECAUTION: Using Nitric Acid (Concentrated Nitric Acid, 68% w/w, available from SEASTAR™ as Instrument Quality or BASELINE®) as an example. Exposure to light or heat can cause Nitric Acid (HNO3) to break down to Nitrigen Dioxide (NO2 - a major component of smog), Nitrigen Dioxide forms an equilibrium with DiNitrigen Tetroxide (N2O4). Proper storage and handling is critical when using these products, consult your Material Safety Data Sheet (MSDS).
5) Assay: Refers to the concentration of the product and is expressed in terms of weight percent. BASELINE® Nitric Acid specifications ensure the customer will receive no less than 67% Nitric Acid (weight Nitric Acid/weight of the Solution x100%, w/w%) and no more than 70% Nitric Acid (w/w%)
6) Test: we have referred to non instrumental or classical techniques as tests. For example the Assay is determined by titrimetry or titration.
7) Analyte: the substance being measured. The principle technique for all the trace metals is Mass Spectrometry (ICP-MS, SEASTAR™'s instrumentation includes both a high resolution Mass Spectrometer - Finnigan's Element 2 double focusing magnetic sector field ICP-MS as well as a brand new Agilent 7500cs ICP-MS, September 2005 Octopole with a Reaction Cell).
8) Maximum Specification: the maximum certified value of an analyte. BASELINE® Nitric Acid certifies or guarantees that Iron (Fe) will contain no more than 20 ppt (parts per trillion or 20 pg/g, 20pg of Fe within 1 g of solution)
9) Actual Value: the measured value in a particular lot analyis
10) Unit(s): ppm - part per million or mg (microgram) of analyte per gram of solution, ppb - part per billion or ng (nanogram) of analyte per gram of solution, ppt - part per trillion or rg (picogram) of analyte per gram of solution
11) Conditional Statement: Instrument Quality products are analyzed at the point of bottling, hence prior to storage in the packaging material (mainly glass or polyethylene bottles). BASELINE® products are analyzed in their packaging material (most products are packaged in specially manufactured Teflon® Bottles, followed by extensive surface leaching. This results in very little change from stored product to packaged product. SEASTAR™ certifies the BASELINE® packaged product. Both products are guaranteed, the IQ statement mentions analytes affected by the packaging material. These analytes may rise above the certified value. If these analytes are critical in you application/analysis it is recommended to use the BASELINE® product for such analytes.
12) Grade: SEASTAR™ produces two main product lines, Instrument Quality and BASELINE®. Both products certify approximately 60 trace metals, the Instrument Quality product is used with most trace metal applications certified values of most analytes being 1ppb or 0.5ppb. The BASELINE® is for our most demanding customers or our premium grade. Most trace metals are below 100ppt with critical environmental metals certified in the 10 and 20ppt range.
