Airport security has strict rules and prohibitions on liquids. Scanners can detect liquids, metals, and drugs, and create 3D x-ray images of luggage. The INSIGHT100 Raman spectrometer is used as a liquid explosive detection system (LEDS) at many airports. Airports are also testing new types of scanners that can detect liquids without the need for travellers to remove them from their bags.

X-ray machines
The INSIGHT100 Raman spectrometer is another type of technology used to detect liquids at airport security. It is used as a liquid explosive detection system (LEDS) and has a very low false alarm rate.
In some cases, airport security staff may use a swab to test the outside of your hand luggage for traces of prohibited substances. This is done by liberally swabbing the outside of your bag and then inserting the swab into a machine for analysis.

3D x-ray machines
Airport security uses 3D x-ray machines to scan liquids and other valuables. These machines can create a 3D x-ray image of your valuables, and staff can see clearly through them. The machines can detect liquids, metals, and drugs hidden in luggage or clothing. They can also detect gold because gold is a metallic object with low conductivity, so the high-frequency radiation of the scanner will see it easily.
The 3D x-ray machines are safe for children and pregnant women. The full-body scanner bounces the radiation back, and the person being scanned is not harmed. However, if you have any concerns, you can request to speak to the police or staff and refuse to be passed through the scanner. The airport management will then check you first, and after complete and thorough checking, you can return to your flight.
In addition to 3D x-ray machines, other technologies are used to detect liquids and potential explosives. For example, the INSIGHT100 Raman spectrometer has been used as a liquid explosive detection system (LEDS) at many European and non-European airports. This technology has a high reliability of results and an extremely low false alarm rate.
There are strict rules and prohibitions on liquids in airports. Passengers are not allowed to carry more than 100 ml of juice, and it should be packed in plastic bags and visible. Not following these rules can result in your luggage being hand-inspected by security, which can cause delays.

Raman spectrometers
Airport security uses X-ray machines to detect liquids in luggage. These machines create 3D images of the contents of luggage, allowing security staff to see clearly through them.
Some airports also use Raman spectrometers to detect explosives in liquids. The INSIGHT100 Raman spectrometer has been used as a liquid explosive detection system (LEDS) at many European and non-European airports. It has a high reliability of results and an extremely low false alarm rate.

Metal detectors
The INSIGHT100 Raman spectrometer has been used as a liquid explosive detection system (LEDS) at many European and non-European airports. It is used to check containers with liquids that passengers want to take on board for potential explosives. However, complementary technology is needed to check metallic containers.

Full-body scanners
The INSIGHT100 Raman spectrometer has been used as a liquid explosive detection system (LEDS) at many European and non-European airports. It checks containers with liquids that passengers want to take on board for potential explosives. Its high reliability of results and extremely low false alarm rate are impressive. However, complementary technology is needed to check metallic containers.
A new type of scanner is currently being tested at Heathrow Airport that will hopefully speed the security process up. More sophisticated scanning technology would eliminate the need for travellers to remove liquids, as well as electronic items and laptops, from their bags.

Frequently asked questions
Airport security uses x-ray machines to detect liquids in your luggage. The newly designed AIT scanners can create a 3D x-ray image of your valuables, and the staff can see clearly through them.
This depends on the country. In some countries, this will not raise any issues. In others, your luggage will be placed on a separate conveyor belt or pointed out by the security officer manning the machine, and will be hand-inspected by airport security staff.
If airport security detects liquids in your luggage, they will enforce the rules. This may include confiscating the liquids or asking you to dispose of them.
There are strict rules and prohibitions on liquids in airports. You are not allowed to carry more than 100ml of juice; it should be packed in plastic bags and visible.
