 mini-pam
1983, walz chief scientist, Germany Wuerzburger University professor ulrich schreiber design and manufacture the world's first modulation fluorometer --pam-101/102/103, and plant physiology, ecology, agriculture, forestry, aquatic widely used in biology and other fields, publishing a large number of high-level research literature. However, the instruments were cumbersome and difficult to the field.
In 1992, ulrich schreiber professors designed and manufactured the world's first portable modulated fluorescence - pam-2000 (now upgraded to pam-2100), both in the room because of its use, also convenient for field use, so after 10 years to become the world's most popular modulation fluorescence.
In 1996, walz in concentrated pam-2000 functionality, based on the design and manufacture of a more portable and ultra-portable modulated fluorescence - mini-pam. The instrument function of pam-2000 has been concentrated, more suitable for field operation, while the price is cheaper.
System Description
mini-pam uses a unique modulation and saturation pulse technology, which can be _select_ive in situ measurements of chlorophyll fluorescence to detect changes in plant photosynthesis. mini-pam modulated measuring light is low enough, you can only stimulate pigment background fluorescence without causing any of photosynthesis, which can record the real basis of fluorescent fo. mini-pam highly sensitive and _select_ive so that even in a strong, without the filter processing environment (such as full sun or even 10000 μmol m-2 s-1 saturation light intensity) is also fluorescence yield can be measured without interference. mini-pam is a powerful tool for field studies of photosynthesis.
Modulated chlorophyll fluorescence ultra-portable mini-pam is characterized by rapid, reliable measurement of photosynthesis, the actual photochemical quantum yield of energy conversion. In addition, mini-pam pam adhering walz family of products has always been the company benefits through the application of modulated measuring light to _select_ively measure the in vivo chlorophyll fluorescence. Based on innovative optical design and advanced microprocessor technology, mini-pam in achieving ultra-portable design and can be sensitive and reliable results. At the same time, mini-pam's very simple.
Measuring photosynthetic quantum yield of only one button (start) can operate, the instrument will automatically measure the fluorescence yield (f) and maximum fluorescence (fm), and calculate the photosynthetic quantum yield (y = Δf / fm), obtained data on the LCD displayed on the screen and automatically stored. In addition, there are many mini-pam mode (mode) menu, including analysis of fluorescence quenching (qp, qn and npq) and record the light response curve, in order to meet customers' specific needs.
Light-adapted leaf folder to connect 2030-b, you can measure the photosynthetic active radiation (par), leaf temperature and relative electron transport rate (retr). Built-in battery production to meet the 1000 quantum measurement needs, the instrument memory can store up to 4000 data.
wincontrol windows operating software for data transfer, data analysis and remote operation.
The standard version of the mini-pam uses red as the measurement light. According to user needs, we can also provide Blu-ray (470 nm) as a measure of light mini-pam.
Feature
1) The reputation of the condensed version of pam-2000
2) compact, accurate, rapid, easy-to-advanced testing equipment photosynthesis
3) stand-alone operation (with built-in computer), can be connected to an external computer operation (windows operating software wincontrol)
4) The ultra-portable design with LCD display and 8 keys
5) The powerful data collection, analysis and storage capabilities
6) low energy consumption, built-in lithium battery can meet the needs of field work a long time, and can connect an external 12 v battery
7) to choose from a variety of leaf folder, patented design of the light-adapted leaf folder 2030-b can simultaneously record and temperature change par
8) The source _select_ion: natural light, built-in light (provided by measuring light, actinic light and saturation pulses), an optional external halogen light source (especially suitable for field studies)
Function
1) can be measured fluorescence induction curve and the quenching analysis (fo, fm, fv / fm, f, fm ', Δf / fm', qp, qn, npq, retr, par, and leaf temperature, etc.)
2) metering and rapid light curve response curve (rlc)
3) 51 built-mode menu, convenient parameter _set_ting and standard measurement
4) on-line monitoring of plants, algae, lichens, mosses and other changes in photosynthesis
5) powerful, especially for field operations, laboratory use wincontrol control program can be self
Applications
Equipment specially designed for outdoor use, can be used to study the mechanism of photosynthesis, various environmental factors (light, temperature, nutrition, etc.) on the physiological state of plants, plant stress resistance (drought, cold, heat, floods, uv, viruses, pollution, heavy metals, etc.), plant long-term ecological changes. In plant physiology, plant ecology, plant pathology, agronomy, forestry, horticulture, aquatic biology, environmental science, toxicology, microalgae biotechnology, the field of polar research, plant photosynthesis has a broad application.
System components
mini-pam basic components include the host (1) and fiber (2). Host built-in high capacity rechargeable lithium battery (12 v / 2 ah), the field operation for a long time (about 1000 times the quantum yield determination). Standard system also includes a battery charger (3) and a "clip from the leaves" (4), and a transport box (5).
Optional accessories include: fluorescence parameters can be measured simultaneously measure the temperature of the light-adapted par and leaf folder 2030-b (6); micro-optical quantum / temperature sensor 2060-m (7), can be used to measure the non-leaf-shaped sample of par and temperature; can install 2030-b or 2060-m tripod st-2101a (8); dark-adapted leaf folder dlc-8 (9), with a vane switch, weight 4 g; micro-fiber (10), can be used to measure micro-sample, or with a portable photosynthesis measurement system gfs-3000 leaf chamber under natural light used in conjunction with simultaneous measurement of gas exchange and chlorophyll fluorescence.
Instrument can be used in conjunction with photosynthesis, simultaneous measurement of gas exchange and fluorescence
mini-pam can use the micro fiber and a portable photosynthesis measurement system gfs-3000 used in conjunction, in completely natural light shade of simultaneous measurements of gas exchange and chlorophyll fluorescence, especially suitable for outdoor physical and ecological studies. |
