Product Description
V-Sorb 4804-A series of specific surface area and pore size analyzer
Features
1) The original cartridge piping systems integration , the use of imported container line , significantly reducing pipeline connection point , greatly reducing the leak rate and improve the ultimate vacuum ;
Less 2 ) modular design , integrated container line , the need to manually connect the components , which will help with the maintenance of the configuration according to user needs and post- upgrade ;
3 ) Germany imported double -stage vacuum pumps, low noise and stable operation, anti-oil back to functional excellence , extreme high vacuum, up 4x10-2Pa (3x10-4Torr).
4) using widely used in industrial control systems , programmable controller solenoid valve control system , anti-interference ability , stability is greatly improved, installation and removal is very convenient;
5 ) The unique design of the test system and the sample line tubing separation structure effectively prevents the impurities generated in the process of sample contamination on the test pipeline .
6 ) Using the same brands of similar products imported high-precision silicon thin film capacitive pressure sensors, pressure measurement accuracy of 0.15% corresponding readings , far better than 0.15% of full scale accuracy (FS) sensor ;
7 ) using eight 0-1000Torr (0-133Kpa), 4 0-1Torr (0-0.133Kpa) pressure sensors, pressure within the test range of segmented measurements, greatly reducing the measurement error under low vacuum , 0 -1Torr silicon thin film pressure sensor accuracy is much higher than the same resistance range Pirani vacuum gauge (usually error of 10% -15 % ) ;
8 ) original cartridge piping systems integration , import container line significantly reduce pipeline connection point , greatly reducing the dead space volume , help to reduce measurement error;
9 ) Stepping original liquid nitrogen surface control system to ensure full test sample tubes in liquid nitrogen surface relative position remains unchanged , the complete elimination of errors due to dead volume changes introduced ;
10) The unique design of the exhaust and intake control system to prevent the sample was evacuated and splash intake process to ensure cleanliness and quality test sample gas path without loss of precision pressure sensor to protect against pressure changes may lead to zero and linear drift.
Technical Parameters
Test function : static volumetric method , adsorption and desorption isotherms measured , BET specific surface area measurements ( single-point and multi-point ), Langmuir specific surface area measurement , BJH total pore volume and pore size analysis , t-plot diagram analysis method microporous outside the MP method microporous analysis , HK micropore analysis method , CO2- ice method microporous analysis , t-plot diagram specific surface area determination; sample true density measurement and the average particle size estimates.
Vacuum System: Cartridge piping and solenoid valve control system, greatly reducing the tubing dead volume space , small changes to improve the detection sensitivity of the adsorbed gas , thus improving the resolution of pore size analysis ; at the same time reducing the manifold pipe connection points greatly improve sealing and instrument life.
Test mode: integrated "Single nitrogen test mode" and " nitrogen + helium standard test mode " in one, for customers to choose according to actual needs ; a " nitrogen + helium standard test mode" , in line with international standards , to ensure that the results of accuracy and consistency, and is easy to operate ; for a sample at a low temperature helium gas can be adsorbed , and not suitable for the determination of the dead volume space helium , through the use of " single nitrogen test mode " to obtain the desired test results.
Calibration gas : with the use of He gas and " nitrogen + empty pipe " mode two kinds of cold free space volume calibration function.
Measuring range : 0.0005 (m2 / g) - to no upper limit (specific surface area ); 0.35nm-2nm ( micropores ), 2nm-500nm ( the holes and big holes ); 0.0001cc / g-- to unlimited (total pore volume ) .
Accuracy: Repeatability specific surface area of ≤ ± 1.0%, the most probable pore repeated deviations ≤0.01nm, the true density of ≤ ± 0.04%; the outer area of ≤ ± 1.5%.
Level Control : V-Sorb original liquid nitrogen surface control system to ensure full test sample tubes in liquid nitrogen surface relative position remains unchanged , the complete elimination of measurement error due to dead volume changes introduced .
Data collection: the use of mainstream storage systems and high-precision data acquisition and highly integrated data acquisition module, the error is small , strong anti-interference ability .
Number of samples : 4 samples can be analyzed simultaneously and four samples degassing treatment , the test samples and sample processing system independent of the system is necessary , and the sample required for the test and sample a degassing treatment can be conducted simultaneously , to avoid the contamination of the test line , thereby further improve the instrument to ensure the accuracy and service life tests.
Control system: PLC solenoid valve control system , high integration and anti-jamming capability , improve instrument stability and service life.
Pressure measurement : A multi- branch imports of silicon thin-film capacitive pressure sensor for pressure measurement segment significantly increased at low P / Po -point precision, 8 0-1000Torr (0-133Kpa), 4 0-1Torr (0 -0.133Kpa), a pressure sensor must provide import test certificate .
Pressure accuracy: imported high-precision silicon thin film capacitive pressure sensor , an accuracy of 0.15% of the actual reading is better than 0.15% of full scale , well above the resistance Pirani vacuum gauge accuracy ( typically error of 10% -15 %).
Vacuum : Imported bipolar vacuum pump can achieve external and internal instrument two kinds of placement , the pump must be built into the instrument, the software can be automatically controlled according to the experimental pump start and stop, thus extending the life of the vacuum pump . Partial pressure range : P / Po accurately controllable range up 5x10-6-0.998. |
