Inspecta for utmost preform quality
Inspecta is the result of Piovan’s commitment to continuous improvement.
After many years of fruitful market presence helping the producers of PET preforms, Medical Plastic Solutions and Packaging for food, acetaldehyde PETes Analyzer has evolved into Inspecta: a precise, reliable and user friendly analyser for detecting the presence of volatile substances inside PET and rPET preforms, sheets, granules and bottles. Inspecta range has recently expanded to include not only Inspecta Ac for Acetaldehyde but also the latest innovation Inspecta Be for Benzene that is essential for all those who use recycled material.
For easy testing every PET shape
- Constant process control
- High levels of accuracy, repeatability and reproducibility
- Ease of use
- Increase of sampling frequency
- Up to 70% cost and time reductions
When a high quality, pure and repetitive production process is requested, Inspecta helps in proving the absence of unintentionally added substances with a close control.
With Inspecta, the analysis is automatic: its software manages all the main functions and settings, operates the instrument, calculates calibration curves and it produces a detailed and clear report that summarises all relevant data and working parameters. This allows the line operators to directly perform the examination process.
Inspecta can be installed close to the production area, with no need for sample collection and transport to a laboratory. The analysis gets aligned to the production timing, allowing for real time results and prompt corrective actions, if needed, with concrete cost savings.
Inspecta in drying process
Acetaldehyde is a colourless volatile with a fruity smell which arises as a by-product of PET thermal degradation by oxidation of the vinyl end group of the polymer chain. In PET bottles, AA is usually present at a few ppm concentration, which is slowly desorbed into the bottle content, altering its taste and aroma.
Benzene is a colourless liquid with a sweet smell which arises as a by-product of PET and Chlorine triggered by processing temperatures. Chlorinated substances decompose at elevated temperature to hydrochloric acid. Basic and acid compounds can catalyse the rearrangement of terephthalic groups in Benzene and CO2 gas. Chlorine is in PVC and its presence in rPET originates from sorting mistakes and packaging components.
