What is the benefit of halogen lamp incorporated in MS/MX/MF/ML?

Heating value per unit of time is higher than other heating method and its useful lifetime is longer for which reasons halogen lamp was chosen. And thus, moisture analyzers with halogen lamp can shorten measurement time taken. Halogen lamp emits much more light than other lamps, which is also beneficial when observing the sample while heating.

What is difference between halogen

and infrared lamp?

How do they relate to each other?

A halogen lamp emits 95 % of light that is within infrared wavelength field and its energy characteristic is basically the same as with infrared lamps.

3

How fast can moisture analyzer with halogen lamp heat up?

It can heat up the pan up to 200C from the ambient temperature within 2 minutes, much faster than by infrared or sheathed heater method.

What is SRA filter like?

SRA stands for Secondary Radiation Assist and is an innovative heating method A&D developed for the MS/MX/MF/ML moisture analyzer. The old method where halogen lamp directly heats sample on a pan, cannot heat the sample evenly because of the difference of the varying distance between the lamp and the sample. SRA improve on this and can heat the sample up evenly with the secondary radiated heat by the glass placed under the lamp, which is placed there in order to emit even heat down to the sample.

What is the benefit of being able to see inside of the analyzer while heating?

Being able to see inside of the analyzer gives users a sense of safety. Not only water in a sample that can be overheated or is burnable may be vaporized but also other material can be carbonized or decomposed. It is very important for users to check by looking at the sample through Progress Window to evaluate the data.

2

What is the minimum measurement time?

It depends on material and moisture content but because MX/MF incorporates 400W halogen lamp as heating source the pan can be heated from ambient temperature to 200C in only 2 minutes. Also, since a SHS^TM sensor designed for analytical balances is installed sensing weight of sample before and after heating is precise and thus, requires less sample volume than before. With appropriate heating temperature and sample mass, measurement can generally be done within a few minutes to 20 minutes. Therefore, for the following reasons MS/MX/MF/ML's heating time and thus, measurement time are shortened.

1. Heating to a set temperature is fast

2. Only very little quantity of sample is needed to measure
