Study of losses... Wrote:(...) Curiously, in Figure 4a, the chromatographic peaks of DNT, close to the LOD (3 ng/mL), were observed. This means that Goma-2 ECO specimens were contaminated before starting the study with trace amounts of DNT. For this reason, contamination should not be attributed only to the laboratory atmosphere because the specimens had been stored in the glass jars as soon as they had been received in the laboratory. The contamination probably begins during the manufacturing process of the explosive. This hypothesis was supported by two facts: the same reactors were used to make both Goma-2 EC and Goma-2 ECO dynamites; and cross-contamination during the storage of the dynamites in the warehouse must not be disregarded.
