Ash Content in Rubber Products

(ASTM D4574 – 06 / ISO 247) 

Ash content of rubber provides direct estimate of amount of fillers present. Amount of filter present is the crucial parameter in deterring physical properties of rubber. Ashing of organic reach and hard to break down products like rubber in traditional furnace requires long durations, sometime ashing proceeds overnight as well. The long times required for ashing are typically due to lack of oxygen for oxidation around samples.  QAsh 1800 , our microwave ashing system from Questron speeds up ashing for organic reach samples up to 10-fold. QAsh 1800 heats faster to desired temperatures using microwave energy. It has software-controlled air inlet in heating chamber which provides oxygen at desired rate and drives away the gases produced during ashing.  QAsh will ash rubber faster and provide consistent ash contents.

Determination of Metal Content in Rubber by Spectroscopy

(ASTM D4004 – 06 / ISO/DIS 6101-6)

By and large two approaches are adopted while determining the Metal content of rubber.

Analysing ash: Ashing is convenient way to get rid of organic matter and to break down the complex matters.  Depending on nature of ash, it can be digested using acid. Acid treatment of ash can be carried out in QBlock series of heating blocks or QLabPro, the microwave digestion system.

Wet Ashing / Charring: Treating rubber with sulphuric acid at 400 ∞C followed by nitric acid is another approach adopted to obtain clear solutions for analysing it on an analytical instrument of choice.

Automation: If you have need to process large number of samples and looking for handling reagents safely Vulcan, the automated digestion system can take care of high throughput requirement in laboratories.
