The XLDS-15 is designed for both, R&D as well as Quality Control/Quality Assurance in Rubber, Polymer and Automotive Industry. Among our customers are Bayer/Lanxess, Volkswagen (VW), University of Qingdao, China, BPSolar (USA), DaimlerChrysler (USA), DIK Deutsches Institut für Kautschuktechnologie (Germany) and others. Different to any other NMR system on the market, it’s unique user interface includes the selection of rubber type to be measured, and accordingly the automatic adjustment of all necessary parameters for measurements and data analysis.
The XLDS-15 doesn't needany air or other gas or liquid for cooling/heating, neither compressed nor dry. Our heating device uses a specially designed heating technique with a direct heating source built directly into the sample chamber . Temperature range is between 40°C and 130°C in the normal mode. The temperature is extremly stable. Temperature variations over weeks are less than 0.1°C. Sample temperature adjustment is within a few minutes, and system is stable within about 10 min after a sudden change in temperature of about 50°C.
IIC offers a high temperature version of the probehead/sample chamber as an option, allowing the on-line investigations of curing and/or aging of elastomer samples at temperatures up to 200°C.
The XLDS-15 uses an electromagnet to generate the static magnetic field. The advantage of this technique over a permanent magnet design is the vanishing magnetic field after switching off the power supply.
No pollution of the magnet poles by metallic dust.
Magnetic field strength freely adjustable is in a small range (13.5 MHz up to 16 MHz).
Measurement of both, 1H as well as 19F possible.
Allows the measurement of fluorinated rubbers and polymers without any further modification or extensive pre-adjustments.
R&D Measurement Mode:
R&D Mode for research and development, Methods, parameters, data analysis tools selectable by user,
Using predefined parameter setups as templates,
Automatic temperature adjustment due to selected rubber type for best results, but can be changed due to user requirements.
Access to programming features for home built measurement or software startegies, user interface modifications and data analysis tools.
QC/QA Measurement Mode
Selection of Rubber Type by User
All parameters incl. measurement temperature and data analysis fully automatic,
Is adjustable by user to virtually any existing type of rubber or polymer,
No further adjustments necessary
Unique Measurement Strategies:
Optimal distribution of tau-values for XLD-, T2-, T1- and T1r-measurements, resulting in an unsurpassed accuracy and reproducibility of results without extending the total measurement time.
Measurement procedures:
T1-APS, using the very fast and extremely accurate APS method for T1 measurements,
T2, using Hahn Spin Echo technique
XLD using Hahn Spin Echo technique
T1r, T1 measurement at a frequency of about 400 kHz, but with the 15 MHz sensitivity, more sensitive to some polymers motions, (other and lower frequencies may also be used)
Multiecho measurements, usually used for liquids and semi-liquid state
Jeener-Brockaert sequence for measuring very slow motions
Lee-Goldburg sequence
Virtually any 1D and Multidimensional relaxation time measurement can be easily adjusted for routine use using our unique template concept.
Software interface and data analysis is based on latest IGOR version, a commercially available software package by Wavemetrics, Lake Oswego, Oregon (www.wavemetrics.com).
IGOR is customized by IIC due to the needs of XLDS-15 applications by adding IIC modules. However, the entire versatility and flexibility of IGOR is maintained and guaranteed.
IGOR is used by NASA, Max-Planck Society, many research institutes and companies, and was rated thebest data analysis software package on the market by the German Society of Physics . Its installation base is by far more than 30,000. Consequently, it is well proven and at least in all our applications completely free of bugs.
Although IGOR's excellence is already proverbial, our modification of IGOR for your particular application provides an incredibly simple to use and very intuitive unified user interface for both, measurements and data analysis.
NMR Hardware:
Based on most recent electronic developments,
using digital signal processors (DSP's) for online processing,
stand alone CPU's and memory for data acquisition,
USB 2.0 connection between PC and Spectrometer, and peripheral devices
Ultrafast and large acquisition memory capacity,
Online adjustment of any parameters and measurement sequences
graphical user interface rather a microprogram language
Macro-controlled batch data acquisition and processing are standard features.,
Automatic measurement and analysis of temperature/time series for aging studies and temperature dependent measurements on samples.
Sample pre-heating by using a second in-built sample chamber:
Avoid time consuming delays caused by waiting periods for samples to reach temperature equilibrium before start of measurement.
(Explanation: Before starting a measurement, the sample needs to be in thermal equilibrium, because molecular motions are strongly dependent on temperature. Placing a sample at room temperature into the sample chamber (probehead) at a measurement temperature of 60°C or even more requires a waiting period of about 5 min to reach temperature equilibrium. By using a second sample chamber included into the probehead, one sample can be measured, while the second sample is already in the preparation period. After the first measurement is done, the second sample can be placed into the sample chamber and measurement can start immediately. There is no further waiting period necessary. A third sample can already be prepared for the next measurement, etc.)
