Analysis of impurities in organic solvents

The aldol reaction progresses under the influence of temperature, humidity, and light! Example of impurity analysis in ethanol and acetone.

This is an example of analyzing impurities detected in a solvent when stored in inappropriate conditions. Ethanol, which was stored in a light-protective reagent bottle in a cool, dark place, was transferred to a used plastic wash bottle and left at room temperature for about a month. As a result, impurities such as triethyl borate and alkylbenzenes were detected. Additionally, acetone stored in a light-protective reagent bottle in a cool, dark place was transferred to a transparent glass bottle without light protection and left at room temperature for about a month, resulting in the detection of diacetone alcohol as an impurity. [Impurity Analysis in Ethanol] - Ethanol stored in a light-protective reagent bottle in a cool, dark place was transferred to a used plastic wash bottle and left at room temperature for about a month (the wash bottle was not sealed as the opening was exposed). - Result: Impurities such as triethyl borate and alkylbenzenes were detected. *For more details, please refer to the PDF document or feel free to contact us.*

Introducing a new device! We present an analytical method aimed at qualitative and quantitative analysis of components contained in samples.

We have introduced the "GC-MS Gas Chromatograph Mass Spectrometer" manufactured by Shimadzu Corporation. This is one of the analytical methods aimed at qualitative and quantitative analysis of components contained in samples, used for the qualitative and quantitative analysis of volatile organic compounds such as parts, materials, residual solvents, and additives. It is necessary for the measurement target to be gasified (with a boiling point below 300°C), but it is suitable for component analysis of mixtures due to its higher sensitivity compared to IR and RAMAN, as well as the ability to separate components in the GC section. 【Overview of GC-MS Equipment】 ■ GC-MS Main Unit: GC-2030, GCMS-QP2020 NX ■ Headspace Sampler: HS-20 ■ Pyrolysis Analyzer: Multi-Shot Pyrolyzer Py-3030 ■ Specifications ・Detection Limit: Several ppm (varies depending on the measurement target) ・Headspace: 40–300°C, sample size 13mm x 40mm or smaller ・Pyrolysis Analyzer: 50–1050°C (EGA measurement compatible), sample size up to 4mm *For more details, please refer to the PDF document or feel free to contact us.

We will introduce examples of comparing the components of color developers contained in thermal paper using solvent extraction!

As a pre-treatment for GC-MS analysis, solvent extraction can sometimes allow for highly sensitive analysis of target substances. This document introduces examples of component comparison of dirt wiped with a cloth and component comparison of color developers contained in thermal paper using solvent extraction. In addition to solvent extraction, we can propose suitable methods from various pre-treatment techniques tailored to your samples and analysis targets, so please feel free to contact us.

We have published an introduction document for the solution "Easy Commuting Expenses," which supports the efficiency of commuting expense management. This document clearly presents the features and benefits of "Easy Commuting Expenses," which enables centralized management of commuting costs, including train, bus, and private car commuting. It streamlines tasks that place a heavy burden on staff, such as determining commuting routes, calculating refunds for commuter passes, responding to fare changes, and managing payment histories, while supporting fair and appropriate commuting expense reimbursements. Additionally, it includes case studies based on the implementation results from over 650 companies nationwide, as well as the effects of cost reduction and operational efficiency. Companies considering a review of commuting expense management or business improvements are encouraged to take a look.

An article has been published regarding the case study of the attendance management system "KING OF TIME" implemented at Nichirei Industrial Co., Ltd. ~ In the case of Nichirei Industrial ~ The workload related to attendance management has decreased. With the transition from analog tasks to automated aggregation of working hours and granting of annual leave, we can now focus on our work with peace of mind. Particularly regarding the "punching method," we utilize fingerprint and facial recognition. By using biometric authentication, impersonation is not possible, and I believe the accuracy of attendance has significantly improved. Transparency has been ensured. 【Case Overview】 ■Challenges Before Implementation - Handwritten attendance sheets were used, resulting in input tasks to incorporate data into the payroll system. ■Key Points of Implementation - Systematization has reduced input tasks. Biometric authentication prevents impersonation. *For more details, please refer to the related links or feel free to contact us.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four configurations: left, center, right, and a total of 12 spots. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor with a single model. 【Recommended for such locations!】 ☑ Entrance facing a busy corridor ☑ Counter or sign near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling or tripping over wired cables × Cable disconnection or damage × Worrying about forgetting to turn the switch back on after temporarily stopping the sensor. × Wanting to be notified of bed exits even from a location far from the nurse call outlet. Such concerns can be resolved simply by connecting our wireless nurse call linked set to the sensor! Our wireless nurse call linked set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed area, alleviating concerns about tripping or falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations far from the nurse call outlet, allowing for more flexible equipment placement.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
