LET`s HAVE a TRY.</strong>
SCiO to detect illegalities in the sport of table tennis? So promising project. Let`s have a try.
ITTF now looking to set up a strict control of the illegal additives to the table tennis rackets (covering rubber sheet).
Dear Consumer Physics team,
We`d like to make our own evaluation of SCiO usefulness.
International Table Tennis Federation (ITTF) is now looking around for the best surest method to detect, identify and ultimately set up a strict control of illegal chemical additives in players` rackets. Here is a corresponding part of the International Table Tennis Regulations
— 126.96.36.199 The racket covering shall be used as it has been authorised by the ITTF
without any physical, chemical or other treatment, changing or modifying playing properties,
friction, outlook, colour, structure, surface, etc; in particular, no additives shall be used.
Regretfully, not all players still obey the rule. Just before a competition starts, some dishonest players used to treat their rubber sheet with a specifical liquid in hope to gain an extra advantage that does utterly contravene the Rule 188.8.131.52, see above.
Below is an exemplary list of the most typical ADDITIVES not allowed to use in the international sport.
ITTF now looking for a reliable apparatus to detect presence of those additives within player`s racket.
— OILS of any nature (mineral, vegetable)
— kerosene (eg. torch oil)
— liquid paraffines (eg. household fuels)
— some cosmetics (eg. baby oil)
Can SCiO device do this job anyway?
Hopefully of best friendly cooperation with you.
in charge of the racket control activities within TTFR.

SOME SPECIFIC QUESTIONS (just to get an initial idea of the SCiO working capabilities).
— Can SCiO detect and identify each of the oily additives if many oil materials were absorbed into the rubber ?
— Can SCiO detect the older oily inclusions into the rubber after oil having got polymerised / oil age oxidation ?
— and so many questions to come. Very promising SCiO device, indeed.
Dear Consumer Physics Friends,
I`m now to communicate to ITTF Equipment Committee and we shall to decide about obtaining a SCiO unit for our practical experiments. It is a new discovery for us, we need to explore it thoroughly.
My early impression: SCiO a mighty spectrometer, it looks to meet our needs pretty well.
Waiting for your response.

For products that exist in our database, and if a relevant application was developed, oily substances can be detected.
Three notes should be taken into consideration. First, in order to develop the molecular sensing model and collect the database, access to samples and their chemical composition information will be needed.
Second, SCiO can identify polymers and plastics, but with limitations.
Colors may change the IR spectrum, making it impossible to identify the rubber (for example, many black rubbers are not only black in the visible, but also in IR, so practically they have no spectral signature for SCiO to measure).
Third, SCiO’s detection threshold is 0.1% or above – i.e. anything below a concentration level of 0.1% may not be detected.
In addition, it will most likely be difficult to detect the oily additives if many oil materials were absorbed into the rubber. This requires further research.
The research can be done using our SCiO Development Toolkit (DevKit), which allows users to create models and apps.
Let us know if you have further questions
