❒ QUALITY RECOGNITION
Chem Service is recognized worldwide for the quality of the materials we provide. We have maintained ISO
9001 and ISO 17025 accreditation. This stringent level of compliance applies to all our internal design,
development, production, distribution, and servicing of organic neat and synthetic reference materials
which we supply to our customers.
✓✓❒❒ QUALITY RECOGNITIONQUALITY RECOGNITION✓✓
❒ QUALITY STANDARDS
Chem Service provides Certificates of Analysis for our Standards Grade pesticide and metabolite
standards in accordance with our internal policy requirements and ISO 9001 and ISO 17025 Quality
System Requirements. Our neat chemical certification policy states that purity and identification must be
established independently by performing three or more (when feasible) separate analyses before we certify
any of our neat products. More than 95% of our neat Standards Grade materials have a certified purity
of 98.0% or greater. Our pesticide standards, whether sold as neat products or as solutions, are certified
for purity, identity, stability, and are traceable by lot.
✓✓❒❒ QUALITY STANDARDSQUALITY STANDARDS✓
❒ QUALITY ASSURANCE
Our internal quality program utilizes our company’s years of experience in providing laboratories with
highly purified materials for reference standards. Our experience has enabled us to identify “problem”
materials that need special attention. For example, any potential peroxide former is tested frequently for
peroxide formation to assure both purity and safety. Moreover, with our expertise in analyte compatibility,
solubility, solution stability, and analysis, Chem Service is uniquely qualified to provide your customized
solutions and mixture standards.
✓✓❒❒ QUALITY ASSURANCEQUALITY ASSURANCE✓
❒ QUALITY TESTING
Our on-going stability testing program for Standards Grade materials has additional benefits for our
customers. We will supply neat standards only when they have a minimum of two-thirds of the shelf-
life remaining on their lot certification. If our stability testing shows the material has a purity or stability
problem which affects its expiration date, we notify our customers and offer a replacement. Chem Service
is committed to supplying quality products and services to our customers.

4. REPLACEMENT POLICY
Prior to the expiration date shown on the label and exclusive of any customer contamination, Chem Service will replace any product showing
purity or concentration degradation. You must advise our Customer Service Department immediately to receive approval and instructions on
either disposal or return of the product. Call 1-800-452-9994.
PRODUCT DOCUMENTATION
CERTIFICATE OF ANALYSIS (COA) - With the purchase of any Chem Service “Standards Grade” environmental, pesticide, organic chemicals,
solutions or mixtures, a COA will be provided free of charge, where available. Please note that “Standards Grade” products assigned a purity
of tech, will not receive a COA. COAs are not available for “Tech Grade” and “No Grade” products, but, where available, these products will
come with an IR.
SAFETY DATA SHEETS (SDS) - English language SDS's are shipped in the box with the chemicals, exceeding OSHA’s requirements. Additional
copies, replacement copies, updated versions, SDS in advance of an order, or additional languages, can be downloaded from our website
www.chemservice.com.
WARNING - READ YOUR SAFETY DATA SHEET BEFORE HANDLING OR USING ANY CHEMICALS.

MakingDilutionsAs one can see, these calculations can be manipulated to allow you to achieve any final volume or concentration you need.
They can also be used to convert to other types of concentrations (weight/weight or volume/volume).
It is often necessary to make a dilution of your chemicals in order to analyze them. Dilutions can be made in one of three
manners: weight/weight, weight/volume and volume/volume. The most common of these is weight/volume. The units of
measurement used are commonly expressed in parts per million (ppm), or parts per billion (ppb). For weight/weight, it is
expressed as 1ppm = 1ug/g, for weight/volume, 1ppm = 1ug/mL, and for volume/volume, 1ppm = 1ul/L. Chem Service
supplies most of their solutions at a concentration of 0.1mg/mL (100ug/mL or 100ppm). In order to make a solution at
a concentration of 100ppm, starting with a pure chemical, you need to know your final volume. Then if the material is a
solid, the calculations are:
0.1mg/mL (final concentration) x 100mL (final volume) = weight of chemical needed (10mg)
FC x FV = W
0.1mg/mL (final conc.) x 100mL (final volume)0.1mg/mL (final conc.) x 100mL (final volume) = volume (number of ul) of chemical needed density (mg/ul)
FC x FV = V
d
If the material is a liquid, it is usually easier to convert to a liquid measurement (i.e. ul), for handling purposes. Therefore,
the density is needed and the calculations are:
0.1mg/mL (initial concentration) x 1mL (volume injected)0.1mg/mL (initial concentration) x 1mL (volume injected) x 1000ug1000ug (conversion factor) = 1ug/mL (final concentration)
100mL (final volume) 1mg
IC x VI x CF = FC
FV
If you need to make a further dilution from a prepared solution, the calculations would be basically the same format. For
example, to dilute 100ppm to 1ppm, take a 1mL aliquot of 0.1mg/mL (100ppm) solution, and dilute to your final volume
(100mL).
The above formula gives the final concentration for the solution. The formula to obtain the volume to inject in order to make
the dilution for this final volume is:
FC x FV x CF = VI
IC
LEGEND
FC = final concentration IC = initial concentration
FV = final volumeFV = final volumeFV VI = volume injected
W = weight neededW = weight neededW CF = conversion factor
d = density V = volume neededV = volume neededV
