NEW ONLINE 700
Automatic process analyser - CE marked
Determination of Air Satured Vapour Pressure on gasolines, completely on line, full automatically, extremely accurately and fast with the New-on-line 700.
The New-on-line 700, making part of the new generation of on-line process analysers, determines Air Satured Vapour Pressure in correlation to the norms, while guaranteeing:
Perennity: conceived in order to have a raised longevity thanks to the good quality of the mechanical, electric and electronic components used for its manufacturing.
Simplicity: a modular architecture of design.
Supervision: accessible by Ethernet network on site or by safe remotely connection made by Internet
Access for user and/or manufacturer
Conviviality: with a clear and didactic graphic interface.
This design brings a maintainability never reached on these analysers and in particular on the ASVP Analysers which don’t require a particular maintenance. New-on-line 700 determines the Air Satured Vapour Pressure in correlation to the ASTM, IP, ISO, DIN standards by using technologies of on-line processes. With a reduced time of analysis (3 – 6 minutes) it allows a constant control in real time of the lines of production. The management of the analyser is completely automatic thanks to the dedicated software which allows the user to supervise and visualize all the parameters referred to the analysis in progress.
Determination of Air Satured Vapour Pressure is made by a precision pressure sensor that measure constantly the absolute value during the test. The analyser, by means of the Lin–Tech software, observes and manages the phenomenon. As soon as the result is obtained, the cell is emptied automatically and a new cycle of analysis starts.
This analyser consists a pressurised enclosure, EEx p for zone 1 and 2, with a CENELEC, ATEX certification and different accessories fixed on both sides of the enclosure.
The protecting system and some EEx d boxes are fixed on the left side, and the analytical part fixed on the right side.
In the upper part of the enclosure accessible with a door supporting a flat screen, are enclosed, the PC, the electronic, the interfaces and the interlock with the terminals.
This analyser is supplied with some components for the sample conditioning procedure. In option, a complete sampling conditioning system dedicated to a user application can be supplied.This analyser has been designed to follow the reference standards methods.
The analytical cell is cooled down with Peltier elements.
This type of analyser has a main application in production unit where the sample composition does not change rapidly in a short period of time.
Principle of Detection
A chamber of 15 ml is maintained at 0.1 kPa and 37.8°C.
A quantity of 3 ml of sample, with a temperature of 0 °C, after the air saturation procedure, is automatically injected by means of a pneumatic injector inside the cell of 15 ml.
Due to the temperature a certain volume of sample changes from the liquid phase to the gas phase.
This mutation modifies the absolute pressure inside the chamber.
When the stabilisation of the pressure is reached, the volume of the absolute pressure obtained will be considered as the total vapour pressure.
Procedure of Analysis
The application software proceeds to the draining first, by flushing the sample to the drain.
This operation takes a few seconds.
The second step is to fill the test tube on a time basis.
When the time of filling is elapsed, a seconde draining procedure can be done if necessary.
Then the analysis is started.
All this procedure of draining and filing takes 5 to 20 seconds depending on the selection made in the set-up software.
The analysis time will takes 3 minutes up to 6 minutes.
The user can select the mode of analysis and also can do alternatively both methods.
The analyser can select a reference sample from one external drum to proceed to the validation of the analyser himself, before to start the analysis on the product line.This type of analyser is specially designed for production unit where the results have to has close as possible of the ASTM reference result from the laboratory.
