Since 1988 Medac Ltd has been
providing an analytical and chemical consultancy service that
specialises in elemental microanalysis to a wide range of sectors.
As a small independent company Medac Ltd offers a dedicated and
highly reliable contract analysis service to biotechnology
companies, chemical companies and academic institutions around the
Every single one of our senior staff has over twenty five years of
experience in the field of chemical analysis and are dedicated in
providing the best possible service to our customers no matter how
large or small the test required.
Medac Ltd can also analysis liquids, solids, organics and inorganics,
organometallic samples, plant and metal materials so whatever your
testing requirements are we will be more than pleased to hear from
CH & N Analysis
This process is carried out by combustion analysis on one of our
elemental analysers. It provides a cost effective means of
establishing sample purity on a vast range of sample types from
polymers through to volatiles. This service offers a same day
turnaround for urgent requests.
Medac provides a Sulfur Analysis service with accuracy within plus
or minus 0.03% absolute and with a detection limit of <0.1%. The
minimum sample size is from 5mg but may also depend on the exact
nature of the sample in question.
We can carry out an Oxygen analysis service on most organic
compounds although those containing quantities of fluorine can
interfere with this process. Normal turnarounds take two days.
We can analyse air sensitive materials and hygroscopic samples
although they do require a slightly longer turnaround time normally
within four working days.
Halogens, iodine bromine, fluorine and chlorine can be analysed by
means of Schoniger flask oxygen combustion followed by titration or
We are able to analyse both metals and non-metals such as
phosphorous using our Varian Vista MPX ICP-OES system. This system
uses the latest technology and software to obtain sensitivity and
high precision results.
Medac is also able to analyse a variety of anions by modern ion
chromatographic (IC) methods. This process is also a powerful
technique for the determination of fluoride anions.
We can measure the water content in a whole range of samples using
our coulometric Karl-Fischer analyser from Metrohm. This process is
ideal for low level detection where the coulometric system can
reliably measure up to approximately 5% water.
Residue on Ignition /Ashing Methods
The process of ashing is the heating of a substance to leave only
the non-combustible inorganic ash and is suitable for samples
containing a significant amount of combustible organic material as a
sample matrix and requires 1g of a sample.
This is only a sample of the wide range of analytical services Medac
Ltd is able to provide so if you would like to find out more please
