ISO 13320 Intelligent Laser Particle Size Analyzer Dry and Wet
Integrated 1. Introduction
The LR-N6200 utilizes the state-of-the-art Mie scattering
principle and convergent Fourier transform optical path.
High-density probe and all-around seamless testing method ensure
the accuracy and repeatability of test results. The unique wet
circulation dispersion system ensures no deposition of particles
during testing and no accumulation of waste liquid after testing
and draining, which guarantees the accuracy of secondary testing
and makes the test results more realistic and reliable. The dry
method adopts linear jet dispersion mode, the sample is dispersed
by high pressure gas and then fly vertically backward, avoiding the
secondary agglomeration of the particles to be measured.
Outstanding optical path auto-calibration system, wet and dry
one-key switching system, dry computer remote control sampling
system, etc., highlights the unique advantages of the LR-N6200.
2. Main performance characteristics
★ Advanced optical path design: NKT6200-B using concentrating Fourier transform testing technology
to ensure the shortest focal length to obtain the maximum range,
effectively improve the resolution of the instrument; The
unique high density detection unit enables 6100 to have super small
particle testing capability. The high density detection unit uses
LR-N6200 to have super full range seamless testing capability.
Full range using a single lens to achieve 0.01 to 2,800m micron
measurement.
★ Fully sealed fiber semiconductor laser: the use of high stability, long life fully sealed imported
fiber semiconductor laser, excellent stability so that it has a
strong test repeatability, life is more than 30,000 hours.
★ Laser power monitoring and automatic adjustment: the exclusive use of constant power laser, real-time
detection of laser power and automatic adjustment function,
effectively avoid long-term use of laser power attenuation
problems. At the same time, constant current, constant voltage
and high filtering laser power supply are used to prolong the life
of laser effectively, and the normal service hours are more than
30,000 hours.
★ Laser intelligent management system: the first to increase the laser intelligent management system,
intelligent management system real-time monitoring of the working
state of the instrument, once received the command of the work of
the intelligent management system will instantly light the laser,
high-performance laser will reach a stable working state in 3
seconds. After the sample test, the intelligent management
system will automatically shut down the laser, and the laser
basically does not decay. Theoretically, the laser can be replaced
for life.
★ Dry and wet one key switch: dry and wet switch will be automatically completed by the
instrument, the whole process is completed within 10s.
★ The main detector Z to automatic movement: after dry and wet switching due to the intervention of
optical glass will lead to focal length changes, LR-N6200 will
automatically adjust the main detector according to the dry and wet
method, so that the main detector is always on the focal plane.
★ Large aperture lens: large aperture Fourier transform lens, more effectively
realize the Fourier transform of optical signal, more accurate,
more effective.
★ Anti-dry burning ultrasonic: LR-N6200 realizes water-free protection of sample pool to
avoid damage to ultrasonic; The ultrasonic power is adjustable
from 0 to 50 watts.
Dustproof and shockproof design: the whole instrument is sealed to
greatly improve the service life of the internal
components. The unique suspension structure can effectively
avoid the interference of external vibration to the instrument, so
that the test results are more stable and reliable.
★ Strong anti-corrosion design (optional) : according to the actual needs of customers can be equipped with
acid resistance, alkali resistance, oil resistance (including all
solvent oil), resistance to organic solvents (such as phenol,
n-hexane and other organic solvents).
★ Imported fiber semiconductor laser: LR-N6200 uses high stability, long life imported high-power
fiber output semiconductor laser, excellent monochrome and
stability so that LR-N6200 has a super repeatability test.
★ Laser intelligent management system: no preheating, on demand switch laser, sample detection after
the laser will automatically shut down, this system can prolong the
service life of the laser and protect the laser from external
interference
★ Automatic calibration of optical path X and Y direction: the instrument can adjust the optical path by itself if the
optical path is slightly changed due to the change of sample
window.
Unique micro circulation system: the whole dispersion circulation
system has been optimized design, the dispersion medium is more
than 150 ml can cycle test, really achieve the micro circulation
test; All joints adopt the design of quick insertion and quick
twist, all pipes can be replaced in a short time; The
optimized design ensures no waste residue after drainage and the
accuracy of the next test result.
★ Wide range: NKT6200-B range dry method reached 0.1μm ~ 2800μm, wet method
0.01μm ~ 2800μm.
★ Free exhaust bubble design: the new design makes the whole test process will not have
bubble into the test sample window, avoid bubble interference.
★ Sample residue free design: the instrument pipeline and drainage structure are optimized
design, the instrument pipeline, circulation pump without liquid
residue, to avoid the impact on the next test data; The dry
test was also designed to be residue free.
★ Dry computer remote control feeding: LR-N6200 dry test test personnel can control the feeding speed
through the computer, greatly reducing the labor intensity of the
test personnel.
★ New upgrade of feeding method: after the upgrade of dispersed good samples directly into the
measurement area, can effectively solve the problem of inaccurate
test results due to the second sample reunion; At present, we
are the only one in China that adopts this method, and the imported
instruments also adopt this method. Other manufacturers also need
to disperse through a hose, which will lead to the reunion of
samples again.
★ Sample window: newly designed sample window quick change device, make sample
window replacement more convenient and fast, easy to switch and
automatic identification, sample pool automatic lock, easy to
switch and maintenance of different dispersed systems
Software: in accordance with pharmacopoeia GMP regulations, with
electronic signature, permission setting, data tracking, data can
not be changed and other functions.
For pharmaceutical industry customers, 3Q certification is
available. 2.
