The measurement of bacterial counts conducted in food bacterial testing is calculated by culturing and counting the number of colonies. However, this method requires time for culturing and cannot evaluate difficult-to-culture bacteria. On the other hand, the real-time PCR method allows for the direct extraction of DNA from samples without culturing, enabling the investigation of the quantity of the target bacteria (DNA copy number). This document presents a case study comparing the bacterial counts obtained through culturing the easily cultured Escherichia coli and the copy numbers measured using the real-time PCR method.

We have completely renewed our homepage. In this renewal, we have revamped the design and structure to make it more user-friendly and comfortable for everyone, while enhancing the information provided. ◆ Key Points of the Renewal - Improved accessibility to information We have reviewed the common navigation across all pages and improved the menu structure to make it easier to understand. The structure allows for intuitive access to the necessary information. - Comfortable viewing in all environments In addition to PCs, we have made the site compatible with various viewing environments, including smartphones and tablets. You can enjoy a comfortable experience regardless of location or device. - Enhanced visual design for better visibility We have reviewed the overall color scheme and layout of the site, refreshing it to a more understandable and sophisticated design. ▼ You can view it here https://www.mst.or.jp/ We would be grateful if you could take a look. We will continue to strive for further enhancement of our content, and we appreciate your continued support.

■What is Supercritical Fluid? A supercritical fluid is a state that exists under conditions of temperature and pressure above the critical point, possessing properties that are intermediate between those of a liquid and a gas (see Figure 1). Supercritical CO2 can be used as a mobile phase in chromatography due to its ease of handling at conditions (7.4 MPa, 31°C). ■Extraction Using Supercritical CO2 In the SFC/MS setup, SFE (Supercritical Fluid Extraction) is connected in the preceding stage, and extraction of components contained in the sample is performed using supercritical CO2. Since the extraction, separation, and detection can be carried out automatically, it is effective for the analysis of components that are sensitive to light, water, and oxygen.

■ A consistent system that accompanies you until resolution and diverse analytical approaches We provide consistent support from hearing about the issues to reporting, collaboratively leading to optimal solutions through dialogue. With over 100 types of analytical methods and AI analysis, we cover challenges across all domains, responding to the trust that "MST is reliable" with flexible responses and proven results. ■ Abundant technical skills and experience We cater to a wide range of needs, from advanced analysis in existing fields like semiconductors to custom analysis in new areas. We have achievements in unique technologies such as the first domestic commercialization of FIB-TEM and SSDP-SIMS. ■ Fairness and reliability Since 1984, during the era when semiconductors took the world by storm, we have walked alongside the forefront of manufacturing. We maintain a fair and neutral stance, building solid trust through quality management based on ISO 9001. ■ Optimal problem-solving through AI analysis We propose solutions tailored to objectives and challenges through equipment analysis, AI analysis, and simulation. By maximizing the use of customer-owned data and designing and constructing custom AI models, we aim to generate results that meet specific needs.
