Welcome to another episode of
Behind the Science, Rockstar edition. I’m your host,
Jennifer Fournier. Sometimes, when I’m taking
the underground subway, I really enjoy listening to
the street performers who make music sound beautiful
in what can sometimes be a dirty place. Portable instruments allow
us to take music anywhere. Wouldn’t it be great if we can
make great scientific music anywhere too? Today, we’re going
to look at a new tool from Waters that makes dirty
samples look a lot cleaner and can be easily
deployed anywhere. Hi, Jeremy! How are you? Hi, Jen! How are you? Great. I’m so glad I found you
because I have a question. Mm-hmm? So now that it’s nice
weather, I love to garden. And what I’m doing
is I’m growing a lot of green
vegetables, but I’m finding that my green
vegetable here with spinach has a lot of holes in it. And what I really
want is how can I get what I get at the
grocery store, which is beautiful green spinach? Oh, that’s because all
the commercial farms, they use pesticide to prevent
bugs from biting it. Remember… Spinach is one of the most
difficult matrices because of all the natural
pigments like chlorophylls. Those are very
difficult to remove, but we have a very
nice chemistry, can be very easy to
use to remove these. Great. Do you want to
know how to do it? I’d love to! Let’s do it! Take a look at your
spinach samples. So typical of what you
see in the spinach sample, the natural pigments
are these compounds. So this is a spinach
extract without cleanup. As you can see, it has a dark
green color, it’s very typical, you can see through it. The typical cleanup
technique involves using a chemical called
graphitized carbon black. It’s very effective in removing most of natural pigments,
but is so effective, sometimes you’re also
removing some pesticides. But on the other hand,
if we’re using PRiME HLB. We’re removing most
of chlorophyll type of natural pigments, but
without losing any pesticides. Wow, Jeremy, that was
really interesting, because I don’t want to
use a lot of pesticides, so to have a method
that I can easily detect the pesticide I use in
my garden is really valuable! So let’s test it right now! OK. Actually, I’ve got an
HLB PRiME syringe here– Oh, no, no, no, Jen! We don’t need a vacuum
manifold, because we have a brand new product
which is called Oasis PRiME HLB in the plus cartridges. We can do this anywhere. You can do that anywhere? Yes. Oh. You can do it on a hike,
you can do it with a kite, Jen? You can even do it on a bike– Jen! Sorry, Jeremy, I was just
thinking of all the places I could do that! OK, but we do have to
do this at the lab– safety first! All right. So what’s the catch? We found a simple, fast,
and effective sample cleanup for pigments such as chlorophyll
that has flexible formats. I finally found the portable
scientific rock band member. Check out the application
note below for more details on what you learned today. And join us next time
for another episode of Behind the Science,
