A toner cartridge for a printer includes a species detection key which forms a part of an outer shape of the cartridge and an IC chip which stores individual information, wherein a part of a harness for connecting to the IC chip or between the IC chip and a connector portion is mounted on the species detection key. A main body of the printer has a key receiving portion which mates with the species detection key. Thereby, the printer can detect erroneous attachment of a cartridge at early stage and surely cope with various types of cartridges requiring only compact space with the aid of its detection means.

The invention provides an interface assembly for delivering an ionized analyte from an ionization apparatus into an ion mobility spectrometer. This allows analysis of biological and non-biological samples, even non-volatile solids, via differential mobility spectrometry, without fragmentation of molecules. The invention also provides portable sample analysis systems that operate at ambient pressure. Systems of the invention may be used for high molecular weight species detection, for example, drinking water contaminants, pathogenic biological agents, bio-organic substances, non-biological material, peptides, proteins, oligonucleotides, polymers, bacteria, and hydrocarbons.

Species detection techniques are described based on measurement of a dynamic response to an external stimulus. One embodiment includes a voltage stimulus applied to a polymer electrolyte fuel cell (PEFC), with the response to said stimulus used to measure CO concentration on the anode catalyst. The principles of symbolic dynamics, finite state machines or a simplified peak response-to-asymptotic value measurement can be used to achieve a high degree of precision for measuring CO concentrations. Using the techniques of the present invention, CO poisoning of a fuel cell can be monitored and diagnosed before reaching a critical condition, thereby allowing early implementation of mitigation or graceful degradation strategies.

Present invention disclosed a novel method for detecting and quantifying target DNA from the biological sample. It provides a method of amplification of DNA sequences with loop-mediated isothermal amplification (LAMP) and its easy and accurate detection and quantification by electrochemiluminescence (ECL) technique. The target LAMP DNA is bound electrostatically with [Ru(bpy)₃]⁺² on the carbon electrode surface, and an ECL reaction is triggered by tripropylamine (TPrA) to yield luminescence. This is a highly sensitive strategy for the detection of sequence-specific DNA from different biological samples at picogram levels. The target DNA of Sus scrofa (pork) meat was detected as low as 1 pg/μL (3.43×10⁻¹ copies/μL) and for Bacillus subtilis DNA samples the detection limit of 10 pg/μL (2.2×10³ copies/μL) was achieved.

An optimizing West Lake Longjing tea tree species detection method on the basis of genetic algorithm is characterized in that: an electronic nose is used to collect finger prints from odors of different species of collected West lake Longjing tea; on the basis of analysis of average finger print and the score plot of the main component, by adopting three key technologies of genetic algorithm, namely the roulette wheel selection, single-point crossover, and simple mutation, and taking the overall recognition rate as the adaptability function, sensors that are contributed to the modeling of tree species are chosen to carry out optimizing combination, thus the required number of sensors for modeling is reduced, at the same time a matrix analysis is carried out for the sensor spectrum responding value through the F value of variance analysis and the main component load.

The invention discloses an environmental DNA macro bar code method for researching a macrobenthic animal community structure. One technical scheme to be protected by the invention is the application of the primer pair in detecting the community structure of the macrobenthos in the water area to be detected. The primer pair is named as COI and is composed of a primer 1 and a primer 2, and the primer 1 and the primer 2 can be a sequence 1 and a sequence 2 in a sequence table.
