Gas Chromatography (GC)

High sensitivity and high resolution: Gas chromatography has high sensitivity and can detect trace substances at the ppm (parts per million) or even ppb (parts per billion) level. Comprehensive two-dimensional gas chromatography (2D GC) achieves orthogonal separation through two columns of different properties and a modulator, greatly improving sensitivity, resolution, and peak capacity.

Improved automation: Modern gas chromatographs widely adopt electronic pressure and flow control systems (EPC), such as Agilent 6890 and Shimadzu GC-2014 models, providing more reliable support for the reproducibility, optimization, and automation of chromatographic conditions. In addition, the new generation Nexis GC-2030 gas chromatograph also has automatic operation functions, such as pre-aging, making the analysis results more stable and reliable.

Development of combined technologies: The combination of gas chromatography with other analytical techniques, such as gas chromatography-mass spectrometry (GC-MS) and gas chromatography-infrared spectroscopy (GC-IR), further improves analytical accuracy and sensitivity, provides richer analytical information, and helps to more accurately analyze the components in complex samples.

Electronic Balance

Sensor Technology: The core technology of electronic balances relies on high-precision sensors. For example, the XP-L series uses a high-speed single-module weighing sensor to improve weighing speed and overload capacity. Mettler Toledo balances use electromagnetic sensor technology to provide microgram-level accuracy (±0.1 µg to ±1 mg), ensuring long-term stability. In addition, some models integrate temperature and humidity sensors to reduce the impact of environmental changes on weighing results.

Automatic Calibration and Internal Calibration Functions: Most electronic balances support automatic calibration, such as through built-in programs or E-Loader software for quick calibration. Internal calibration balances automatically correct according to preset conditions, while external calibration balances require manual use of standard weights. Sartorius balances further provide full-linear four-point calibration to enhance accuracy.

Environmental Adaptability Control: The balance uses a level control system to monitor and alert to tilt status in real time, and anti-vibration design (such as anti-vibration balances) reduces vibration interference. Windshields (such as the BL-F series and ES320's transparent windshields) reduce the impact of airflow. The Mettler HE83 also has an automatic energy-saving mode to reduce energy consumption when idle.

High Precision and Fast Response: Electronic balances achieve high-precision weighing through the principle of electromagnetic force balance. For example, the XP-L series has extremely low repeatability error, while precision electronic balances (such as the BL-F series) can achieve 0.001g readability. The dynamic weighing function (such as the AND GX series) supports real-time tracking of weight changes in moving objects.

Multifunctional Applications: Built-in applications include percentage weighing, density determination, piece counting, etc. Some models support live weighing and bottom hook weighing (such as ES10000 and ES320). Statistical weighing and cumulative weighing functions improve data processing efficiency.
