KATYN 2. Sensational evidence of Russian terrorist attack 4/10 translated into English
6/22/2014 11:14:38 AM
The Polish news portal W Polytice informed on further developments around the Russian terrorist attack near Smolensk, April 10, 2010. In an article entitled "Sensational findings of explosive materials used in 4/10 translated to English. Send them to friends abroad! (Sensacyjne ustalenia ws. Materiałów wybuchowych 10/04 przetłumaczone na angielski. PRZEŚLIJ znajomym za granicą!)", the portal writes:
"Samples of the wreckage of Tu-154 in the hundreds of cases have a high probability of explosives - including RDX, penthrite and TNT. Laboratory tests are to be repeated. As ordered by the prosecution. they were carried out in such a way that nothing was detected.
A Polish weekly, wSieci, shared details of opinions of chemists (Prof. Krystyna Kamiensk-Trela and prof. Slawomir Szymanski), who focused on outrageous mistakes made by government experts.
An English version of the article was published on the Internet, which says in particular (see here):
"The analysis of the evidence samples taken in Smolensk was assigned to the CLKP. Each of the 732 samples was tested by four chromatographic methods: GC / TEA, GC / ECD, GC / MS and HPLC / DAD. It was assumed - in a way incomprehensible to the independent chemists - that the presence of explosives would be confirmed only in case of detection of their presence through each of the four adopted methods. So, if three were positive, and one negative, it was arbitrarily assumed that the sample does not contain traces of explosive substances.
- This is like searching for an alibi, as no one uses such methods. Was it to dodge the conclusion that unfortunately something is not right with these samples? - asks Professor Szymański.
- Let us begin with the analysis of the first of these four methods, as it concerns the most bizarre inconsistency it resulted in. TEA detector (Thermal Energy Analyzer) is most sensitive to detect chemical compounds that were sought and has the highest selectivity. Above all, it only reacts to the presence of compounds containing nitrogen, which is present in most explosives.
Therefore, it is impossible to explain how this particular device - that was used in testing of the investigated material - was able to detect in about 100 samples more than 350 instances of the occurrence of substances which by the CLKP experts were interpreted as being Phthalates, Hydrocarbons, Terpenes or Esters of Phosphoric Acid. None of these substances contain nitrogen!
In order to have not 100%, but 200% certainty that the findings presented by the prosecutor's office are phony, the researchers conducted a simple experiment. They contacted the manufacturer of the gas detector (the very same type used by the CLKP). They requested that this manufacturer suggests a suitable TEA (Thermal Energy Analyzer) device that would allow the determination of the presence of these types of substances; as these were alleged to have been detected by the CLKP with the use of this very device.
The US manufacturer of this device responded that it is unable to help. Their detectors are not designed for that purpose, and there is not a chance that their equipment can detect them. Therefore, either the American manufacturer doesn't know what it makes and what it sales, or the Polish experts presented false test results.
What then, could the TEA detector show? In most cases the signals were characteristic of Hexogen (RDX), one of the most powerful explosives present in the popular mixture of C4, among others.
According to prof. Kamieńska-Trela and prof. Szymanski, the claim by the CLKP experts that the signal compatible with that of RDX observed in the chromatograms obtained by GC / TEA comes from Diisobutyl Phthalate is most discrediting in the light of the most basic knowledge of the operation of the TEA detector.
Similar conclusions can be derived by analyzing chromatograms made during the ECD (Electron Capture Detector) detections - up to 150 samples showed signals consistent with the pattern of RDX.
What did the CLKP experts do with these many repeated and confirmed detections you ask? They ignored all of them.
This coincidence is especially important when you consider where the above-mentioned samples came from. Extraordinarily frequent readings of RDX concerned swabs taken from the seats covers of TU-154M; these seat covers were found in a shed near the crash site. This shed offered favorable climatic conditions to preserve the traces of explosives for months after the tragedy - until the Russians allowed Polish experts to conduct testing on Siewiernyi aerodrome. Among other compounds PETN and TNT were also detected".
