&If the combustion head is not installed in the system or connected incorrectly, the flame cannot be ignited.
&If the flame suddenly goes out, the gas supply valve will automatically shut off.
&Pressure sensors monitor and regulate air pressure to maintain a continuous and stable combustion state of the flame. If the air pressure is too low, the flame will automatically extinguish.
&If there is a power outage, the flame will automatically extinguish. Power requirement: 220Vac& nbsp 50/60Hz,&nbsp 3&nbsp A
&Automatic monitoring of the liquid level in the collector. If the liquid level is too low, the flame will automatically extinguish and ignition will be prohibited.

&For Aurora, security is always the highest principle, ensuring that users conduct experiments in a safe and reliable working environment. The instrument has many computer-controlled safety features, including automatic selection and replacement of auxiliary gas; Program control of gas flow rate; Automatic ignition; Instant status of flames, etc. Aurora regards these as essential configurations for the instrument, indicating its emphasis on safety.

&Aurora AI 1200 graphite furnace atomic absorption adopts transverse graphite furnace heating technology (THIGF), ensuring a very uniform temperature distribution throughout the entire graphite furnace tube. Combining this technology, AI 1200 avoids the common problems of ordinary GF methods, ensuring isothermal distribution in time and space. The digitally controlled graphite furnace power supply enables the heating rate of the graphite furnace tube to reach 3800 K/s.
★ Eliminated the "memory effect", including some refractory metal elements.
★ Provides lower atomization temperature and shorter atomization time, extending the service life of graphite furnace tubes.
The higher atomization efficiency results in higher sensitivity, and the resulting peak pattern is narrow and high.
★ Reduced chemical and background interference.
Simplified the sample operation steps.
&The AI 1200 adopts a uniquely designed temperature probe, which is not only used for high temperature measurement, but also suitable for low temperature range. The temperature accuracy can reach 1 ℃, ensuring that the instrument can control the temperature in a wide range. The test results obtained from this are the most objective and accurate.
&In recent years, Aurora has been committed to researching new technologies and application areas of AAS. It has invented the patent for Capacitive Coupled Plasma Graphite Furnace (CCP-GF)& This technology combines both graphite furnace atomic absorption spectroscopy and inductively coupled plasma atomic emission spectroscopy (ICP-AES). If AI 1200 is paired with CCP-GF, it will become a new type of AI 2200, which can be used for metal and non-metal multi-element analysis and will be very outstanding.

&AI 1200 Flame/GF Flame/Graphite Furnace Atomic Absorption is an instrument that combines two testing methods into one.
The characteristics of the flame are as follows:
&Nebulizer made of Teflon material.
&Nbsp&nbsp Online dilution.
&Nbsp&nbspSafety Chain.
The characteristics of graphite furnace are as follows:
&Horizontal heating graphite furnace tube.
&High heating rate.
&Built in power supply. Power requirement: 220Vac& nbsp 50/60&nbsp Hz,&nbsp 30A

&The design of the atomizer for the 1200 flame and graphite furnace allows users to quickly switch between the two methods. The latest 'Quick Switch' technology makes switching work faster and more convenient, even completing it in seconds. Aurora also offers the option of "Automatic Switch", which can automatically switch to the flame or graphite furnace platform with just one button.

&In order to simplify operations and improve efficiency& All AI 1200 includes the following automated platforms:;
1. Choose from 5 programmable light sources.
2. Hollow cathode lamp (HCL) automatic positioning.
3. Wavelength program control.
4. Program control of slit width and height.
5. Gas type and gas flow rate program control.
&With the development of technology, more and more users demand to maximize the analysis efficiency of instruments. Therefore, it is crucial to adopt appropriate techniques to calibrate the background.

&The AI 1200 series offers two different background correction techniques, namely Smith Hieftje background correction and deuterium lamp background correction.
&The Smith Hieftje calibration technology is a standard configuration of the AI 1200 product, featuring simplicity, low cost, and high efficiency. This method uses the same light source as the analyte signal measurement, so no additional hardware or optical system is required.
&Deuterium lamp background correction is relatively more expensive, but its performance is excellent. In the application field of atomic absorption, it has become an increasingly important and reliable background correction technique.
&In summary, Aurora's atomic absorption has excellent detection and sensitivity:
The space of the hollow cathode lamp and deuterium lamp beams overlaps with each other, and extremely high backgrounds can also be corrected.
High frequency modulation ensures high-speed signal measurement.
High speed data acquisition with time-resolved background correction.
The high-intensity light source and efficient optical system ensure a high signal-to-noise ratio of the instrument.

Outstanding Human Computer Interaction Interface - AISPECTM Software
&nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp
&The design principles of the software used in AI 1200 are easy to use, large development space, wide applicability, and strong customization capabilities. Its standard Windows interface is very easy to master, and users do not need to spend more time and money on training. The analysis templates included in the software are also very flexible to use, with a three-step operation of selecting experimental methods, injecting samples, and pressing buttons, which is very convenient.
&This software will quickly adjust the instrument according to the actual situation during use. Therefore, no matter how complex the user's experiment is or how high the control requirements are, you only need to press "Set" and "Go" to maximize the potential of the instrument. You can also customize your own display window according to your analysis needs.
&Aurora's software is non analog and reflects in real-time the temperature, total absorbance, corrected absorbance, background absorbance, and other data contained in each interrelated peak graph. Each data can be interpreted separately.
Real time graphical display and data collection mean reliability and consistency in analysis. AI 1200 GF uses temperature sensors that are suitable for the entire high and low temperature range, resulting in directly measured temperature values rather than approximate calculations.
&AISPECTM software is based on LIMS (Laboratory Information Management System) support and can easily exchange sample information in different data formats. Users can also add their personal information as a reference for the output report. An important application of LIMS is to add barcodes to each event, so that all data is stored in their respective attribution. Some competing brands claim to also support LIMS systems, but they only conditionally select some important data, not all of them. Therefore, users can add some supplementary information to the test results at any time, which can only be achieved through Aurora's software.

Universal XYZ 3D automatic sampler

&Aurora's XYZ fully automatic sampler can be used in atomic absorption instruments such as flame method (F), graphite furnace method (GF), steam generation method (VG), etc. This type of injector, which can be positioned and moved freely in three-dimensional space, has more comprehensive functions and greater uses than rotary injectors. It can be applied to almost all different sample containers:
Enzyme linked immunosorbent assay (ELISA) plate
Standard test tube
■ Graphite furnace sample cup
Customized graphite furnace sample container
Under the control of Aurora's AISPEC software, the XYZ automatic sampler has:
◆ Automatically dilute from a single standard sample and generate a working curve
The digital micro pump can automatically dilute the sample to the allowable measurement range.
The desktop driving method can complete online sample preparation, while samples, standards, improvers, blank samples, etc. can be mixed in any way, so it can adapt to higher technological development and quality control requirements.
The rapid drying technology includes user programs such as sample injection speed, preheating temperature, cooling time, etc. It can achieve a level of preheating and cooling temperature below 150 ℃ and analysis time below 20 seconds, which means it has a high efficiency of completing 3 samples in 1 minute.

Steam/Hydrogen Generator

&VG 411 can improve the sensitivity of detecting sub trace levels of mercury or hydrides, reduce interference and detection limits. Aurora's revolutionary design on gas-liquid separators ensures perfect performance in such tests. The three-stage solution mixer provides operators with a wide range of choices. VG 411 is not only suitable for Aurora's AI 1200 atomic absorption series and AI 3200 atomic fluorescence series, but also for other brands of AAS, AFS, ICP-AES, and ICP-MS instruments.
