HPLC: High-Performance Liquid Chromatography

GPC (Gel Permeation Chromatography) is one of the separation modes of HPLC and is a method for evaluating the molecular weight of polymer compounds. It can determine several average molecular weights (Mn), weight average molecular weight (Mw), and polydispersity (Mw/Mn) in a single analysis, and it is also possible to compare the distribution profiles. It is also referred to as SEC (Size Exclusion Chromatography).

Qualitative analysis by simultaneous measurement of fluorescence and mass.

Fluorescent dyes are used in commercial clothing, detergents, paints, etc., due to their effect of increasing apparent whiteness by absorbing ultraviolet light and emitting visible light (fluorescence). In this case study, we attempted to qualitatively analyze the fluorescent whitening agents contained in laundry detergents by connecting a fluorescence detector (FL) and a mass spectrometer (MS) to the liquid chromatography (LC). As a result, we were able to identify peaks that emit fluorescence from the numerous peaks detected by MS, and further estimation of the components was possible through the analysis of the MS spectra. By connecting FL and MS, it is possible to determine the presence of fluorescent components and estimate the components in a single measurement.

"Tissue Tubes" are tubes with a capacity of 3.0ml and a rack lid locking feature. Each tube has a 2D code on the bottom, allowing you to use a 2D scanner to reflect the code in a PC database, enabling efficient management of sample information. Additionally, by using our dedicated rack that holds 24 tubes, you can read the 2D codes on the bottom of the tubes in bulk. 【Features】 - The inner diameter at the mouth is wide at 13.4mm, the height is low at 25.9mm, and the inner bottom is flat, making it easy to insert and remove samples. - Particularly suitable for samples of tissue pieces/cell pieces ranging from 5mm to 7mm. - Using our dedicated rack that holds 24 tubes allows for bulk reading of the 2D codes on the bottom of the tubes. - Compatible with automatic machines due to its SBS format. *For more details, please download the PDF or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
