If only small quantities of valuable products or toxic material from a few to 1,000 micrograms are to be analysed, the micro-dosing device Sympatec ASPIROS can be applied. ASPIROS is mounted instead of the RODOS funnel and can be used in HELOS or as ASPIROS/L version also in QICPIC applications.

Sympatec ASPIROS, micro dosing system

A constant sample mass-flow is of decisive importance for powerful dry dispersing. The controlled vibratory feeding unit Sympatec VIBRI, equipped with a built in amplitude controller feeds dry powders from 1 mg to 1,000 g constantly and independent of the load in the VIBRI funnel. VIBRI will be used with different HELOS dispersing units and as VIBRI/L also with QICPIC dispersing units in the laboratory. Using the on-line analyzers MYTOS or PICTOS with the dosing device VIBRI has the advantage of ensuring a well-defined and constant sample flow into the analysing system.
