MAICO Ver 1.00

Hello, I'm MAICO.

I will help you to find the best instrument for you!!!

OK, See you next time!!!


How large is your sample

My sample is larger than 1μm.
(Micro particles)

My sample is smaller than 1μm.
(Nano particles)

Do you have enough number of particles?

Many enough for size distribution analysis.

I want to measure a few particles in a pure water, or clean room air.

Where do you want to measure?

I want to measure in the lab.

I want to measure on-line/in-line in the factory.

High throughput, repeatability/ High accuracy, resolution

High throughput measurement with a few minutes/sample is preferable.

I want to count each particle to obtain accurate and high resolution particle size distribution.

Zeta Potential measurement

I want to measure zeta potential as well as
the particle size.

Zeta potential measurement is not necessary.

Molecular weight/ Particle count

I want to measure absolute molecular weight and
hydro-dynamic diameter using liquid chromatography.

I want to count the number of each nano-particles
with each size

Connection to liquid chromatography

I want to measure the size/molecular weight with a liquid chromatography,
to get continuous data, as well as the stand-alone measurement

Just stand-alone measurement is enough.

Identification of the particle/ measurement range

I want to count 2 different particles with different density, respectively.

I want to measure particles down to 30nm.

Volume based measurement / number based measurement

Volume based measurement with high throughput
and good repeatability is preferable.

Number based measurement with good accuracy
and high resolution is preferable.

Solid particle or emulsion / Spray mist

I want to measure solid particles, emulsion, or bubble

I want to measure the mist of spray.




Raman spectrum

I want to measure the size and shape parameters for each particles

I want to measure the size and shape parameters
and their Raman spectrum, to identify each particles.

Measurement range / probe type

I want to monitor the particles, mainly over1μm,
which is going through a tubing.

I want to measure particles over 50μm, in a tank or tubing, using very robust measuring probe.

Imaging analysis / Electric resistance

I want to measure the particles using imaging analysis,
to get shape information of the particles.

I want to count the particles by electric
conductivity information.

Auto sampler

Auto sampler is NOT necessary.

Auto sampler is necessary.
