1
So to use the GC, we're going to click Huser, and then look at this icon right here called GC Solution.
2
That's the one we're going to use, but first we have to turn on these gas canisters first.
3
The first one is the air, then the nitrogen.
4
Finally, it will turn on the hydrogen.
5
Next, Adam's going to turn on the instrument with a button located on the side.
6
As you can see, all three lights are green.
7
Next, we're going to open the software.
8
We'll click this little icon here.
9
It looks like the instrument and it's under the one.
10
We'll just click OK.
11
That's fine.
12
Click top and we'll go to instrument parameters and then click system on.
13
It says download the instrument parameters.
14
We'll click OK.
15
At this point the instrument will try to heat up and ignite, all you have to do is wait.
16
So your first step is going to be to go to instrument parameters, and you can go file,
17
new method file, and that sets up a new method file.
18
So then what we're going to do is we're going to go to the column
19
this is the column that's in there you don't need to change anything there
20
so that's fine that's okay you can set the temperature of your detector usually
21
we keep ours at 200 degrees Celsius so we'll leave
22
that there this is where you determine your column
23
and it's right here so it starts off at 25 degrees
24
and you can hold it at 25 degrees for let's say one minute
25
and hit enter and then we want it to heat up to 50 degrees
26
so we type in 50 as you can see there
27
and then this is the rate per minute that is going to increase
28
so let's say we want to go up five degrees every minute
29
it's going to stay at 25 degrees for one minute
30
and then go from 25 to 50 over a course of five minutes
31
which is how we get our total program runtime of six minutes once
32
you've set all these parameters to the way you want it.
33
The start temperature is going to be 25 degrees.
34
You just click this download button and it's going to download that method to the instrument.
35
Next we're going to show you how to run a sample, so you go fast processing,
36
batch table wizard, load method file, you select the method file you just created and saved,
37
I didn't you how to save it click next standard unknown
38
we want standard only click next we're going to go ahead
39
and click under standard sample file is going to be zero
40
because we're doing manual injection next this is really where you can do whatever you want you can name the file
41
so we'll name this one test and then for report format file we're going to go to
42
and then we'll click sample and then we'll scroll over to method symbol
43
and that's going to be our report file format
44
and then we'll click finish and now we're ready to go
45
so what we're going to do is we're going to hit start save current batch file we do you type
46
Open the same name as earlier, save, yes, save, okay.
47
And with our sample, we're going to inject it in the injector, show right here.
48
So we put it in, and then we're going to put in one microliter.
49
Alright, once it's in there, we're going to click start on here, and then we immediately have to go to injector and change the temperature.
50
You should go to set.
51
This is why you can't do it, set line config, and then we're going to go to line 1 and click enter, and then click return.
52
And now your sample is running.
53
After the experiment is completed, it will come up to a file like this,
54
and so what you can see here is where we have our chromatograph,
55
we have acetone, ethanol, butanol, three peaks.
56
To use this data, our first step is going to be to go to data analysis,
57
manual peak integration, and then we're going to remove all the peaks.
58
So you click here, and you click here, from here to here, and it removes all the peaks.
59
Then we're going to insert peaks, so we can go from here to here.
60
And then we'll insert another peak from here to here.
61
And then we'll insert a third peak from here to here.
62
And so those are our three integration values.
63
And then you go report in data, and it sends you a thing like this.
64
Next, we're going to insert a table right here and click OK head, and what you can see here,
65
I don't know if you guys can see it, let me try and zoom in,
66
there you go, can you guys see that,
67
so the table we just inserted, we have our three peaks, one, two, three, and we have the area and the retention time shown,
68
this is the integration area and you can use this to compare them so then we go back
69
and so we know peak one peak two and peak three
70
all right to shut down the instrument all you do is you go to this is the report file
71
so we don't need that
72
you go to instrument parameters there you go system off that's going to shut down the software
73
so you can just hit X.
74
You want to save your method file now you just hit X there
75
and start log off and then to shut the instrument all you have to do is click the button and then
76
So make sure you close the tanks.

Gölgeleme Tekniği Nedir?

Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
