What principles should a mobile laboratory adhere to?

Mobile laboratories frequently involve activities such as moving, transporting, and assembling equipment. They operate independently to carry out tasks in more demanding environmental conditions. During the design process, in addition to meeting the standard requirements for laboratory safety, environment, equipment, methods, material selection, and equipment model selection, the following principles should also be adhered to:
First, multifunctionality. Mobile laboratories typically need to independently carry out specific tasks within a particular industry, thereby developing comprehensive capabilities. For example, a mobile food-testing laboratory is equipped with advanced instruments and devices such as ultra-high-performance liquid chromatographs, portable gas chromatographs, biochip scanners, liquid chromatography-mass spectrometry systems, and ion chromatographs, as well as rapid food safety testing kits, enabling it to essentially cover the detection of toxic substances and residues in food.

Second, compact structural design. Given the relatively limited space available in mobile laboratories, each functional area must be independent and the overall structure must be highly compact. For example, a certain type of mobile laboratory for microbial testing includes a mobile seating area for four staff members, a medical containment chamber with restricted access, an office area, two sample collection boxes and storage areas, a disinfection zone, and wireless network access.

Third, modular combination. Design effective isolation of incompatible activity zones as needed to prevent contamination, interference, or adverse impacts on mobile laboratory activities, thereby ensuring the quality of mobile laboratory operations, personnel safety, and protection of confidential information pertaining to clients and relevant parties. To enhance the functionality of mobile laboratories, laboratory components can be modularized—for example, clean rooms and sterile rooms can be configured as independent modules, while energy, power, water, gas, and communication equipment can be centralized into a single module.

Fourth, ensure self-sufficiency. The mobile laboratory should be equipped with independent systems for power generation, water supply, gas supply, and wastewater treatment, thereby guaranteeing its autonomous operation in field settings. At the same time, the mobile laboratory should be fitted with interfaces for connection to municipal power grids, tap water supplies, and sewage disposal systems, facilitating seamless integration with these utilities during operations. The design of the mobile laboratory should give full consideration to waste collection, thereby preventing contamination of the local natural environment following on-site experiments. Furthermore, the design must thoroughly account for the reliability of critical systems such as power supply, propulsion systems, air conditioning, ventilation, insulated storage units, disinfection systems, and waste disposal systems.

Fifth, adapt to the environment. Mobile laboratories operate in diverse environments and must be able to withstand various climatic conditions, such as drought, extreme high and low temperatures, humid heat, salt spray, electromagnetic interference, and radiation. Environmental adaptability should be factored into the design. The terrain where these labs are deployed can be complex—ranging from mountainous regions and hilly areas to swamps and sandy beaches—and the lab must be able to handle the vibrations generated during various modes of mobile transportation. For sensitive equipment, it is advisable to use air or liquid vibration dampers with superior performance to prevent damage caused by bumps and jolts during transport by car, train, airplane, or ship. Additionally, consider the expansion rates of various pipelines as well as their fixing methods.
Sixth, standardization. A basic standard system for mobile laboratories has been established. This standard system represents a synthesis of the practical experience of scientific and technological workers as well as a reflection on lessons learned from various challenges encountered. When designing mobile laboratories, existing standards should be carefully referenced, and innovation should be pursued on this foundation. Whenever possible, standard parts and universal components should be used; vulnerable parts should be easy to repair and replace. Each model should have its own set of production and maintenance support procedures to ensure ease of repair and use, thereby enhancing efficiency and effectiveness. The selection of vehicles, experimental cabins, experimental equipment, and testing methods—as well as related safety and environmental considerations—must comply with applicable standards.

7. Self-calibration system: Before conducting experiments at the destination, the mobile laboratory must be calibrated first. During the design phase, consideration should be given to equipping the laboratory with appropriate standard samples, algorithms, and icons. Instruments and equipment capable of automatic detection and calibration should be selected, and a laboratory environment monitoring system—both inside and outside the lab—should be installed to ensure that environmental conditions meet experimental requirements.
