2. David Norris Analytical Laboratories
is a privately owned independent
Company established in 2005 with
the specific aim of offering specialist
formulation storage stability trials
and 5 batch analysis.
(For further information in respect of 5 batch
please see our separate leaflet or contact us.)
3. OUR LABORATORIES
The Company was established and is owned and managed
by David and Kirsty Norris.
We fully understand the needs of both the client and

Our expertise includes analytical reports for registration in
Europe, North America, South America, Asia and Australia.
Our aim is to provide high quality analytical services in an
efficient and cost effective manner. We are committed to
a flexible approach, putting our clients first and ensuring
our services are tailored to meet client’s needs.

We are extremely proud to be a
member of the GLP programme.
4. FORMULATION STORAGE STABILITY
We can offer a full range of tests to meet CRD
requirements for all formulation types.
We offer stability testing on herbicides, pesticides and
biocides. Our range of analytical equipment allows us to
assay synthetic chemicals and natural plant extracts along
with inorganic salts. We are adept at developing methods
for materials which have mixed active ingredients or exist
as a complex blend of chemicals.
We are fully equipped to conduct CIPAC and EEC testing
for formulation storage stability trials. We can offer expert
help in failed formulation studies with explanations of why
the material failed the associated test and guidance on how
the formulation might be improved.
The formulation tests we can offer include:
(but are not limited to)
AUTO FLAMMABILITY
FLAMMABILITY
OXIDISING ABILITY
pH AND DENSITY MEASUREMENTS
ACCELERATED STORAGE
VISCOSITY, SURFACE TENSION MEASUREMENTS
WETTABILITY, FOAMING
SUSPENSION PROPERTIES
PARTICLE SIZE ANALYSIS
We have conducted various storage stability studies looking
for specified toxic impurities and breakdown products from the
active ingredient in the formulation. This is becoming increasingly
important and we offer free advice to try to ensure that clients
are looking for the correct compounds in the storage trial.
5. TECHNICAL MATERIAL STORAGE STABILITY
A full range of standard tests necessary to determine
both the chemical and physical nature of technical materials
are available. These include OECD, US EPA, OPPTS and
EEC methods.
We offer a range of storage conditions including 54, 40,
35 and zero degrees plus freeze thaw cycles.
The technical material tests we can offer include:
(but are not limited to)
SOLUBILITY IN WATER AND ORGANIC SOLVENTS
PARTITION COEFFICIENT (N-OCTANOL/WATER)
VAPOUR PRESSURE
DIRECT PHOTOLYSIS
CORROSION RESISTANCE
HYDROLYSIS
MELTING AND BOILING POINT
CHEMICAL INCOMPATIBILITY
STABILITY OF PACKING MATERIAL
To address regulatory criteria for formal validation, we
offer three levels of validation. The shortest reflects the
Sanco guidelines, the next level reflects a Europe wide
validation and the third reflects a World wide validation
reported to EPA format.
