HORIBA LA-300 laser particle size analyzer

The LA-300 laser scattering particle size distribution analyzer is a laser particle size distribution analyzer based on the Mie scattering theory. Mie scattering theory is a classical theory obtained strictly according to the mathematical solution of Maxwell's electromagnetic field theory, and is currently the most rigorous calculation method used in laser particle size analyzers. Therefore, using this calculation method provides a theoretical guarantee for the instrument to provide reliable data results. At the same time, Horiba Manufacturing's excellent technology and years of experience in developing laser particle size analyzers ensure the high precision, high resolution, low maintenance, ease of operation, and a series of other outstanding performance of the LA-300 laser particle size analyzer.

Lightweight and convenient in size

Horiba has successfully reduced the size of the instrument by 30% while ensuring high quality, making the LA-300 lightweight at only 25 kilograms, truly meeting the increasingly tight laboratory space situation and more suitable for the heavy workload of various complex laboratories.

Fast and accurate measurement

The LA-300 not only ensures the detection of different types of substances, but also adopts special detection methods, greatly reducing the detection time. It only takes 20 seconds from measurement to obtain accurate results. In addition, the instrument is also equipped with a safe operation mode to ensure that the correct methods are used during testing. The built-in automatic collimation function gives the LA-300 unparalleled high repeatability, which ensures constant and consistent system operating conditions.

Use to save labor

The precision and efficiency of LA-300 do not necessarily mean complex operation, on the contrary, the design strives for simple and easy operation and maintenance. Firstly, in terms of software design, a user-friendly and easy to maintain interface has been provided, and a series of designs have been set up to maximize the savings of human effort. Especially the chart user interface can provide you with clear and accurate dialog boxes, allowing users to complete common operations by simply pressing the command keys and a series of shortcut keys they need.

Automatic measurement function

The operation and control of LA-300 are all carried out through computers, and it also has unique learning functions. By using this function, users can program and store the conditions and operating procedures for daily routine testing in a simple language. During testing, users only need to press a key, and the instrument can automatically perform testing according to the pre programmed program. This feature is more effective for users who choose automatic samplers for continuous detection, as it has built-in automatic sorting software to ensure high repeatability of the instrument. In addition, the instrument is equipped with an automatic calibration button and uses a multi-dimensional automatic search and positioning system to determine whether the photodiode and optical system should be repositioned and automatically calibrated.

Operation security and confidentiality

The operation of LA-300 also has confidentiality, and its software can help the project supervision system operate the instrument according to the path determined by the user. The project supervision system can identify the scope of users and the personal identities of commonly used users. Users can log in with their names and passwords, ensuring the confidentiality of operations.

The sample is evenly dispersed

The LA-300 sample dispersion system uses 15W in addition to mechanical stirring, The 28KHz ultrasonic device ensures that the sample can be uniformly dispersed. The high flow centrifugal circulation pump (5.5L/min) not only ensures high-speed stable circulation and uniform sample suspension, but also reduces dust accumulation due to high flow rate, thus eliminating frequent pump replacement. The dispersion tank (including mechanical stirring device), ultrasonic dispersion head, and circulation pipeline of LA-300 are all built in, which greatly improves the simplicity and stability of operation and greatly reduces maintenance. In addition, all parts of the instrument that come into contact with liquids are made of materials that are resistant to chemical corrosion and rust, ensuring low maintenance.

Powerful software functionality

The instrument software adopts a Windows 98/95 interface, and data processing can be integrated with Word, Excel and other application software are interoperable. And different report formats can be printed according to user needs. The powerful computing function of the instrument is one of the most outstanding qualities of LA-300, In addition to providing data and curves on the particle size distribution, integration curve, MEDIAN value, and MEAN value of the sample, LA-300 can also provide the cumulative distribution of 10 particle sizes of interest to the user and the corresponding particle size values for the 10 cumulative distributions of interest. The 10 particle sizes of interest and the 10 cumulative distributions of interest only need to be entered by the user in the display conditions. After one detection, users can obtain four different distribution results based on particle volume, area, particle size, and quantity according to their needs. The acquisition of these four distribution results only requires four simple choices in the display conditions, and does not require four detections. Another special feature is that users can simultaneously import the distribution maps of several tests into one screen and display them in different colors, so that users can compare and analyze the results of several tests.

In addition to the above functions, LA-300 also has other rich software features. The real-time display function enables users to see the process of the distribution curve changing with the progress of detection while detecting, thereby determining whether the detection conditions are appropriate and the effects of other influencing factors; The print format preset function allows users to change the display and print format of data and graphics according to their preferences; The confidentiality function facilitates internal management for users; The 3D display of up to 300 detection results makes the graphic display more intuitive, and also includes contour display function.

Wide measurement range

The LA-300 adopts a unique long-life semiconductor laser light source and a large diameter lens system, combined with Horiba's proprietary high-performance detector, enabling the instrument to measure particle sizes ranging from 0.1-600um without any optical adjustment. Such a large measurement range allows users to conduct deeper basic research, product quality control, and more.

High performance detector

Horiba company took the lead in using a special 650nm laser, six wide-angle side and rear detectors, and a 36 channel ring-shaped silicon light matrix photodiode detection target for the measurement part, which can simultaneously process 42 data signals. By calculating the electrical signal converted from the density of scattered light, the distribution of particles can be determined. Therefore, this measurement method based on Mie theory can ensure the accuracy of the obtained data.
