Quality & Certificates (CoA)

All articles are manufactured inside Europe

The products are of the highest purity available on the market. 

Purity values are min. 97-99% as a rule.

Our quality is based on competence and experience obtained from years being in industrial pharmaceutical and agrochemical research.

All our compounds are provided with either COA, HPLC-MS / H-NMR analytics as standard feature.

Confidentiality on all projects is taken for granted.

We import the raw materials from pertinent  countries (Indonesia, India, Malaysia, China, Russia)

Third party laboratories test every batch of raw material  using multiple methods of analysis to test the purity, including:

High Performance Liquid Chromatography (HPLC)

Near-Infrared Spectroscopy (NIRS)

Polarimetry

Titration

One can find the method of analysis directly on each Certificate of Analysis  (COA) product 

If not available, ask us using the chat or by mail admin(at)mondialk.com and we will add it

Understanding Spectroscopy

  Spectroscopy></p><p>
	<strong></strong>Spectroscopy studies the
interactions between matter and light. It can give insight into the identity
and purity of a sample compared to a library of standards. For many labs,
Fourier transform Infrared Spectroscopy (FTIR) is the preferred method for
infrared spectroscopy. In infrared spectroscopy, the scientist shines infrared
radiation through a sample. Some of the radiation passes through, while some of
the radiation gets absorbed by the sample. This creates a visual spectrum that
offers a representation of the sample’s unique molecular transmission and
absorption. This shows:</p><ul>
<li>Unknown materials
present in the sample
</li></p><li>The consistency
and quality of the sample
</li></p><li>The amount of
individual components in the sample
</li></ul><p>
	The FTIR is not always
the best option for dietary supplements or nootropic compounds, though. For
example, two FTIR spectrums of a natural extract will appear to be similar. The
FTIR is able to recognize the major components, like cellulose, in a plant but
not differentiate minute changes in the active ingredients of the two extracts.
Another limitation of the FTIR are when molecular interactions occur in a
wavelength below 1500 nm, which are more difficult to analyze on a typical FTIR
spectrum.</p><p>
	In situations where the
FTIR may not be the appropriate method of analysis, the lab may use any
combination of the following techniques:</p><ul>
<li>Near-Infrared
Spectroscopy (NIRS)-generates a spectrum for wavelengths 700 nm to 2500 nm,
including the wavelengths that are undecipherable on an FTIR
</li></p><li>Ultraviolet/Visible
Spectrophotometry-measures the reflectance of excitable atoms in a compound
</li></p><li>Proton Nuclear
Magnetic Resonance Spectroscopy (NMR)-identifies the number of protons and
their location in the molecular structure
</li></p><li>Inductively
Coupled Plasma Mass Spectrometry (ICP-MS)-detects low levels of heavy metals up
to one part per quadrillion.

Separated Bands on Chromatographic Plates

High-performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. Each component in the sample interacts slightly differently with the adsorbent material, causing different flow rates for the different components and leading to the separation of the components as they flow out of the column. HPLC allows scientists to separate, identify, and quantify compounds in any sample that can be dissolved in liquid.
