So to use the GC, we're going to click Huser, and then look at this icon right here called GC Solution.

That's the one we're going to use, but first we have to turn on these gas canisters first.

The first one is the air, then the nitrogen.

Finally, it will turn on the hydrogen.

Next, Adam's going to turn on the instrument with a button located on the side.

As you can see, all three lights are green.

Next, we're going to open the software.

We'll click this little icon here.

It looks like the instrument and it's under the one.

We'll just click OK.

That's fine.

Click top and we'll go to instrument parameters and then click system on.

It says download the instrument parameters.

We'll click OK.

At this point the instrument will try to heat up and ignite, all you have to do is wait.

So your first step is going to be to go to instrument parameters, and you can go file,

new method file, and that sets up a new method file.

So then what we're going to do is we're going to go to the column

this is the column that's in there you don't need to change anything there

so that's fine that's okay you can set the temperature of your detector usually

we keep ours at 200 degrees Celsius so we'll leave

that there this is where you determine your column

and it's right here so it starts off at 25 degrees

and you can hold it at 25 degrees for let's say one minute

and hit enter and then we want it to heat up to 50 degrees

so we type in 50 as you can see there

and then this is the rate per minute that is going to increase

so let's say we want to go up five degrees every minute

it's going to stay at 25 degrees for one minute

and then go from 25 to 50 over a course of five minutes

which is how we get our total program runtime of six minutes once

you've set all these parameters to the way you want it.

The start temperature is going to be 25 degrees.

You just click this download button and it's going to download that method to the instrument.

Next we're going to show you how to run a sample, so you go fast processing,

batch table wizard, load method file, you select the method file you just created and saved,

I didn't you how to save it click next standard unknown

we want standard only click next we're going to go ahead

and click under standard sample file is going to be zero

because we're doing manual injection next this is really where you can do whatever you want you can name the file

so we'll name this one test and then for report format file we're going to go to

and then we'll click sample and then we'll scroll over to method symbol

and that's going to be our report file format

and then we'll click finish and now we're ready to go

so what we're going to do is we're going to hit start save current batch file we do you type

Open the same name as earlier, save, yes, save, okay.

And with our sample, we're going to inject it in the injector, show right here.

So we put it in, and then we're going to put in one microliter.

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.

You should go to set.

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.

And now your sample is running.

After the experiment is completed, it will come up to a file like this,

and so what you can see here is where we have our chromatograph,

we have acetone, ethanol, butanol, three peaks.

To use this data, our first step is going to be to go to data analysis,

manual peak integration, and then we're going to remove all the peaks.

So you click here, and you click here, from here to here, and it removes all the peaks.

Then we're going to insert peaks, so we can go from here to here.

And then we'll insert another peak from here to here.

And then we'll insert a third peak from here to here.

And so those are our three integration values.

And then you go report in data, and it sends you a thing like this.

Next, we're going to insert a table right here and click OK head, and what you can see here,

I don't know if you guys can see it, let me try and zoom in,

there you go, can you guys see that,

so the table we just inserted, we have our three peaks, one, two, three, and we have the area and the retention time shown,

this is the integration area and you can use this to compare them so then we go back

and so we know peak one peak two and peak three

all right to shut down the instrument all you do is you go to this is the report file

so we don't need that

you go to instrument parameters there you go system off that's going to shut down the software

so you can just hit X.

You want to save your method file now you just hit X there

and start log off and then to shut the instrument all you have to do is click the button and then

So make sure you close the tanks.

इस पाठ की शब्दावली और बोलने के सुझाव

यह स्पीकिंग पाठ वीडियो “GC FID Operational Tutorial” पर आधारित है। सबसे ज़्यादा दोहराए गए शब्द ये हैं: click, file, peak, instrument, degrees। इस वीडियो में शैडोइंग के लिए 76 वाक्य और 953 शब्द हैं। बोला गया हिस्सा 7:12 लंबा है। वक्ता लगभग 132 शब्द प्रति मिनट की स्थिर गति से बोलता है, जो शैडोइंग के लिए आरामदायक है। 91% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली आसान है।

इस वीडियो की मुख्य शब्दावली

वीडियो के 15 सीखने लायक शब्द, उच्चारण और अर्थ के साथ:

ध्यान देने योग्य उच्चारण

वक्ता 36 बार संक्षिप्त रूपों का प्रयोग करता है, जैसे we're, we'll, don't। इन्हें वैसे ही छोटा बोलें जैसा आप सुनते हैं।

“sh” और “zh” की ध्वनियाँ: integration /ˌɪn.tɪˈɡɹeɪ.ʃən/, injection /ɪnˈd͡ʒɛk.ʃən/, retention /ɹɪˈtɛnʃən/
लंबे शब्द — बलाघात सही रखें: parameter /pəˈɹæm.ə.tɚ/, integration /ˌɪn.tɪˈɡɹeɪ.ʃən/, experiment /ɪkˈspɛɹ.ə.mənt/, chromatograph /kɹoʊˈmæ.toʊˌɡɹæf/

हिंदी भाषियों के लिए मुश्किल ध्वनियाँ:

/z/ — इसे “ज” (/dʒ/) न बनाएँ: wizard /ˈwɪzɚd/, zoom /zuːm/
/æ/ — “ऐ” से ज़्यादा खुला: parameter /pəˈɹæm.ə.tɚ/, format /ˈfɔːɹ.mæt/, manual /ˈmæn.j(u)əl/, batch /bæt͡ʃ/, acetone /ˈæ.sə.toʊn/

इस वीडियो से अभ्यास कैसे करें

पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
सामान्य गति पर एक-एक वाक्य की शैडोइंग करें और हर वाक्य तब तक दोहराएँ जब तक आपकी लय वक्ता से न मिल जाए।
अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर instrument, parameter, column जैसे शब्दों पर ध्यान दें।

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
