Key Features:

The highest resolution in the same level of UV: 1nm
UV-1800 easily meets the wavelength resolution requirements of the European Pharmacopoeia. Using a spectroscope with Czerny Turner device, obtain a compact and bright optical system. Stray light, wavelength repeatability, and baseline stability have also been improved to meet user needs.
Small footprint: 450W x 490D (mm)
Using a Czerny Turner spectroscope, it has a smaller volume than the old model UV-1700 and occupies about 15% less space.
Data can be saved on a USB drive and processed by a computer
Single machine UV-1800, equipped with UV Probe computer processing software as standard. The data measured by UV-1800 can be saved in USB memory, and the data can be processed and printed by computer and software UV Probe. UV-1800 has the advantages of single machine UV such as easy operation and small footprint, as well as the performance of computer-controlled UV.
Computer controlled
It can be controlled by a computer through a USB interface. UV-1800 has a USB interface that has become a standard interface for computers and can be controlled by most commercial computers.
USB printer
PCL compliant USB interface printers can be used as UV-1800 printers, increasing the number of available printers.

1. Photometric measurement

Measure the absorbance, transmittance, and energy of the sample at a fixed wavelength

2. Quantitative measurement

Two fitting methods: first-order and first-order zero crossing

Establishing standard curves using three methods: coefficient method, standard sample input, and standard sample input

Establish A=K1 * C K0, which can search for raw data, graph curves, and set parameters. Save 240 sets of curves, each set of curves can test 240 pieces of data

3. Multi wavelength

Zui can test the transmittance and absorbance of samples at 8 different wavelengths

4. Dynamics

Measure the absorbance or transmittance of the test sample at a fixed wavelength point over a period of timeVariation spectrum, which can calculate the sample reaction rate △A/tScanning time.The sampling interval, delay time, and wavelength point can be set according to actual needs

Operating procedures for UV-1800 UV visible spectrophotometer:

1、 Power on:

1. First, connect the power to the UV detector, turn on the switch button (the instrument starts automatic scanning), and turn on the computer.

2. Double click the "UVProbe2.35" icon on the desktop, open the software, enter "admin" in the username bar, and click "OK".

3. Click on the "Connect" icon in the bottom corner to complete the instrument scan. Click "OK" ->"OK", then press the "enter" ->"F4" button on the UV detector, and click the "Connect" button on the computer.

2、 Method setting:

1. Click on the circled M (method) in the upper right corner of the screen, enter the wavelength scanning range (wavelength range 1100-190), select the scanning speed (usually Medium), and the scanning mode is usually set to "Single" by default. Press the "OK" button.

2. Press "Baseline" to bring up a dialog box, click "OK".

Press the "Go To WL" button, enter the wavelength "750" as shown in the figure below, and click "OK".

Press' Auto Zero 'again to perform automatic zeroing.

3、 Sample testing

1. Add blank solution and perform baseline scan.

Attention: Place the sample colorimetric dish on the outer side (close to the operator), and place the blank colorimetric dish on the inner side. Both colorimetric dishes are filled with blank solution.

2. Place the sample solution into the sample pool for sample measurement and click "Start"; After the absorption curve is completed, a window will pop up, and the measured data file will be named and saved to a folder.

3. Click on the "peak pick" icon in the upper right corner, and the maximum absorption wavelength of the measured substance can be seen from the table in the upper left corner.

4. Click on the "Report" icon, select the desired content in the left column, and generate a report.

5. Shutdown: First, turn off the computer, then press the "return" button of the UV instrument to return to the main interface, turn off the instrument switch, and unplug the power.

4、 Attention:

When starting the UV instrument, check if the light source is normal. Generally, it needs to be preheated for 1-2 hours to reduce measurement errors.

When calibrating the baseline, both the colorimetric dish containing the blank solution and the colorimetric dish containing the sample should be filled with blank solution, and the colorimetric dish containing the blank solution should be placed inside; Corrosive liquids cannot be placed in the sample pool; The two smooth surfaces of the colorimetric dish are prone to corrosion and should not be touched by hand; Use paired colorimetric dishes for each measurement.

When "Go To WL" is used to zero the absorbance, the wavelength can be selected as 750 or 500nm, usually 750nm.

When the UV detector is turned off, you need to first press the "return" button to return to the main interface, and then turn off the instrument switch.
